In 2026, with how much money their is in aviation, it seems wild to not have digitized this ages ago. The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
That ATC still takes place over radio just seems insane at this point. And there's pretty much no way to make ATC's job not stressful, its inherently stressful. Taking out how much of their job is held in the current operators mind versus being 'committed' seems like low hanging fruit 30 years ago.
The whole system's just begging for human error to occur. There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
Air traffic (and ground traffic) control are not simple problems. La Guardia has 350k aircraft operations (takeoffs and landings) every year. 1000/day. Peak traffic is almost certainly more than 1 plane every minute. Runways are always in use and the idea that some simple software will solve all the safety problems is not grounded in reality.
One jet landing every minute, coordinating the airspace for miles around the airport, along with coordinating non-landing traffic (helicopters, small craft), while making sure these (already heavily automated) flight systems dont get confused and kill several hundred people sounds easy to you, along with keeping everything on time and schedule?
You say it “…sounds like a simple problem,” and sure, if you think this is a computer problem, it sounds simple. But if all you’re getting back is indignant sputtering, that’s your cue to explain why it’s simple—explaining something simple shouldn't be hard. What do you actually know?
It takes all of two minutes of Wikipedia reading for me to understand why this isn’t simple; why it's actually extremely not simple! If you ignore the incumbency, the regulations, the training requirements, the retrofitting, the verification, the international coordination, and the existing unfathomably reliable systems built out of past tragedies, then sure, it’s "simple". But then, if you're ignoring those things, you’re not really solving the problem, are you?
while making sure these (already heavily automated) flight systems dont get confused and kill several hundred people
Confusion is indeed a common side effect of a job done halfway.
Replying:
I'm really confused at the point you're trying to make - you declared yourself not an expert in this field, while loudly declaring it's so easy to automate.
Because we've already done harder things. 1000 takeoffs and landings per day equals a trillion machine cycles between events... on the phone in your pocket. It is an extraordinary claim, requiring extraordinary proof, to say that this task isn't suitable for automation.
Why don't you do it then? What am I missing?
I'm not qualified to do it, I didn't say I was, and in any event, I don't work for free. I'm asking for concrete reasons why it's not feasible. Spoiler: there are no reasons, only excuses.
> I'm asking for concrete reasons why it's not feasible. Spoiler: there are no reasons, only excuses.
It sounds like you're not asking anything at all
Just to play it out a bit, are you imagining that a pilot would be reporting a mechanical failure upon descent into busy airspace to some type of like AI voice agent, who will then orchestrate other aircraft out of the way (and not into each other) while also coaching the crippled aircraft out of the sky?
Are you imagining some vast simplification that obviates the need for such capability? Because that doesn't seem simple at all to me.
I'm really confused at the point you're trying to make - you declared yourself not an expert in this field, while loudly declaring it's so easy to automate. Why don't you do it then? What am I missing?
I know this was rhetorical but the obvious answer is a complete lack of any actual ideas. “Just automate it” is a common refrain from people who don’t know how to fix the actual issues with any domain.
Remember how we installed traffic lights all over the roads and now car crashes never happen any more at intersections? Truly automation solves all problems.
> Every time I've asked what's so hard about automating ATC
Why don’t you describe the hypothetical automation you believe would solve the problems then?
My hunch is that either your ideas are already implemented (like GP post who said they need to add red lights at the runway instances, except yeah, they do have that), or they are just bad.
> indignant sputtering and patronizing hand-waving.
Preemptively insulting everyone who might respond to you certainly looks like you’re asking for a real conversation. :|
Your accusation of “patronizing hand-waving” is especially off base considering you literally proposed nothing except “automating”. Hand waving indeed.
> The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
It does, the Runway Status Lights System uses radar to identify when the runway is in use and shows a solid bright red bar at every entrance to the runway. I'm curious what the NTSB has to say about it for this incident. From the charts LGA does have RWSLs. I didn't check NOTAM to see if they were out of service though.
Emergency vehicles almost always can override/ignore warning devices (think firetrucks running red lights) which can cause "fun" for some value of "death/dismemberment/vehicle loss".
> That ATC still takes place over radio just seems insane at this point.
Voice communication is insane? I suspect you are ignorant of what it is like to actually fly a large aircraft into a busy airport. Fault-tolerant and highly available hardware must facilitate low-latency, single-threaded communication with high semantic density in order to achieve multi-dimensional consensus in a safety-critical, heterogeneous, adversarial environment.
How would you exactly "digitize"? While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
> While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
Traffic lights instead of mad max intersections are better.
Then there's subway Automatic Train Control.
I don't know that Air Traffic Control staff don't have computer systems for establishing which plane owns what airspace. They at least did do it manually already following specific processes, so it can be at least augmented and a computer can check for conflicts automatically (if it isn't already). And, sure, ATC could still use radio, but there could be a digital standard for ensuring everybody has access to all local airspace data. Or maybe that wouldn't help.
Your ground vehicle wanting to cross a runway could have the driver punch "cross runway 5" button (cross-referenced with GPS) and try to grab an immediate 30 second mutex on it. The computer can check that the runway is not allocated in that time (i.e. it could be allocated 2 minutes in the future, and that would be fine).
But, as pointed out elsewhere, obviously some of this is already present: stop lights are supposed to be present at this intersection.
I'm sure the NTSB report will cover why this didn't stop the accident. Presumably either the system wasn't working as-expected, or the fire truck proceeded despite the warning lights since they had clearance from the controller.
The system is only advisory at present, so if the truck did see a warning light and proceeded anyway, they were technically permitted to do so.
>In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
1700 incursions a year, and other articles mentioning multiple near misses a week at a single airport [1]. It is safe in practice, likely largely due to the pilots here also being heavily trained and looking for mistakes, but it seems a lot like rolling the dice for a bad day.
>I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
I didn't say it'd be free. Just hard to believe radio voice communication is the best way to go.
The problem with the analogy is that aviation has no equivalent to "maintain a safe following distance" or "pull over and come to a stop". If a plane is on an active runway, or in flight, it's generally compelled by physics to keep moving forward one way or another. An automated system that prevented the truck from entering the runway would have been great, but an automated system that falsely reported a truck on the runway might have caused a disaster by forcing the plane into dangerous maneuvers to avoid it.
Lmao the one hope I have for this country is that I know for sure that the American people will rise up to put a violent end to techbros once they try to “ ban non self driving cars”
> There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
How many runways crossings are there in a year? How much is "1700+" a percentage of that total?
The point is that it doesn't matter what percentage of the total they are, it's that 1 is too high without adequate explanation (the Gimli Glider caused vehicles to be guilty of a runway incursion by turning an abandoned runway into an active one, for example).
And the cost of investigating 1,700 should be within the budget.
ATC recording on https://www.liveatc.net/recordings.php
Fire truck was cleared to cross and then told to stop. I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller.
Which, as a non informed person but someone who needs to travel by plane, sounds absolutely insane. Was it always possible to staff that with a single person or is that a result of understaffing?
As an informed person (PPL flying single engine into smallish towered airports all the time), it is absolutely insane for an airport the size of LGA. Occasionally, you will encounter one guy doing tower and ground at very small class D airports or during not-so-busy shifts.
To play devil's advocate, ASEL into small deltas is significantly different than receiving full-stop IFRs late at night.
This small mistake (and it is initially small, just catastrophic) is a system breakdown, not necessarily a staffing breakdown. Though staffing is definitely a wider issue in the NAS.
I fly out of a small-to-medium-sized airport in Canada and I've never seen it happen. The idea of one person being responsible for both tower and ground in the busiest airspace in the US is absolute insanity.
That seems unusual to me. It’s common at smaller airports, but for a big one like LaGuardia I’d think tower and ground would be two different controllers, even lateish at night like this was. I know there has been a staffing problem for controllers in the NY area for some time.
But think of the money they saved by not having to pay another air traffic controller! A controller's yearly salary is the cost of about 10 seconds of the Iran war, based on the recently-reported figure of $11.3B for six days.
New York State is large. It has lots of airports [0] - although not all of those are towered, you're still dividing that 260 down by quite a lot. And I don't believe it's standard practice to fly some dude in Buffalo down to NYC to cover a shift. There's a huge staffing problem in ATC right now.
That staffing problem mostly comes down to it being demanding work that's poorly compensated for the amount of skill and education and stress involved; there are high hiring standards, you can't work past 56, and you can't even get started if you're past 31. If you're interested in aviation, you can make far more money as a pilot and it's a much more pleasant job; why would anyone become an ATC?
>you're still dividing that 260 down by quite a lot
No you're not.
In the state of New York, the most it could possibly be divided down is by 32.
And that only in the case that ATC are distributed to towered facilities equally whether commercial or simple public-use. Which we both know they are not.
And I'll do you a really big favor and not even mention the fact that there are wayyy more than 260 ATC in New York state. Again, I was just being friendly to your view. I strongly suspect that you are also aware that there are well over 1000.
260/32 is around 8. "A lot" is subjective but I think that fits the bill?
LGA is open 16 hours a day, seven days a week. Of course this is an extreme over-simplification, but if LGA only had eight ATC at their disposal total it's easy to see - or at least, much easier to see than if your working number is 260 - how they might have only one guy available to work Tower/Ground on a night shift. Please bear in mind that there's more to ATC in an airspace like NYC's than just Tower/Ground, and that ATC need regular breaks. Maybe they had two people but no redundancy, so one guy was covering both tasks during a break?
Do you know how many towered facilities there are in New York state?
32.
Let's assume only 260 ATC for 32 towers. (Not true, but again, we're being friendly to the conspiracy nuts.) We'll further assume every tower is staffed equally. (Also not true, but again, friendly to the nuts.)
8 Controllers for each tower if those assumptions were true. Which they are not.
Why is one controller on duty in a commercial airport? Not a public-use airport, a commercial airport?
The problem is that you're comparing numbers from before Trump's presidency, but the understaffing of FAA ATCs goes all the way back to when the Reagan administration fired all ATCs to break up the union and forbade the FAA from rehiring any former union members.
The FAA has been playing catch up with training enough ATCs to meet demand ever since, which isn't helped by a sequence of bad decisions made regarding ATC training schools.
This sounds like a right-wing conspiracy theory. Are you saying that, in order to hire more black people, the FAA deliberately created a test only black people could pass? Do you have any evidence of this assertion?
The only domain I recognize is Newsweek, and given the nature of astroturfing, I’m not going to trust domains I don’t recognize.
All the Newsweek article says is that a lawsuit was filed. It doesn’t support GP’s claim that the FAA made “an impossible test, and gave black people the answers.” A lawsuit isn’t evidence of wrongdoing; it’s only evidence of an accusation of wrongdoing.
Looking at the front page of 2 of those domains ( tracingwoodgrains, blockedandreported ) they are ... ah .. not exactly impartial. Sample headlines: "How Wikipedia Whitewashes Mao - The Anatomy of Ideological Capture" and "The Politics of Misery - Why are young liberals so depressed".
The simpleflying link gives the name of the person filing the lawsuit as this character: https://en.wikipedia.org/wiki/Adam_Laxalt who is also ... not exactly impartial, seeing as he "was the Republican party nominee for governor of Nevada in the 2018 election". And as other searches suggest, no stranger to frivolous litigation or false claims.
In summary, spending 5 minutes digging into it gives every impression of it being culture war nonsense.
"The lawsuit doesn’t allege incompetent controllers were hired instead of CTI graduates. Instead, it states that the CTI graduates weren’t given the opportunity to demonstrate their competency."
It sounds like they hired different people, rather than fewer.
Not a pilot or a controller, just a nerd. My take from reading about it was that a large number of high performing potential ATC controllers who had followed the traditional pipeline were ditched. Ofc it's possible they hired exactly as many ppl as they would have otherwise, but in any job with a long lead time for training, a sudden change in the pipeline is going to cause ripples further on for years to come. Maybe the ppl they did hire had a higher attrition rate so that while they had the same # of ppl in the short term, in the long term, they faced shortages. Maybe some % of those they did hire required some % of extra supervision or training. Ofc not insurmountable or fatal, it just means extra pressure that will exert itself in some fashion for years to come after the initial disruption. I have no idea of last night's incident could be considered downstream of the testing change, I was just responding to the allegation that it was a conspiracy theory, however I also don't think it's implausible that it contributed to it in some indirect way.
Maybe the ppl they hired had a lower attrition rate! Maybe the people hired required less supervision and training than the CTI graduates would have! Maybe this had rippling effects on increasing their hiring pipeline as people of color were more likely to see opportunities here.
Your comment presuming it was at best neutral, and any likely change was for the worse is exactly what racism looks like.
> I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller
I remember late last year, couple of months ago, US ATC controllers were without pay but forced to work anyways (similar to TSA I suppose, although I don't think they were forced, but volunteered to work without salary), is that still the situation? Couldn't find any updates about that the situation been resolved, nor any updates that it's ongoing, if so though it feels like it'd be related to the amount of available controllers.
The US has had trouble keeping enough controllers. It's a skilled but extremely stressful job, and so retention would always be difficult but the US also works hard to make it suck more than it should, and of course the over-work from not having enough people makes that even worse.
But no, AIUI only things that were somehow deemed part of "Homeland Security" are frozen, the TSA are part of Homeland Security but the ATC are under the FAA. So this particular partial government funding lapse wasn't causal, at least directly.
ATCs weren't exactly forced to work: they aren't slaves and are free to quit any time. But if they didn't show up for assigned shifts even though they weren't getting paid then they were subject to disciplinary action including termination. Some of them called in sick, or took on temporary second jobs to bring in some cash (obviously a bad thing from a fatigue management standpoint). After the government shutdown they were paid in arrears for all of the hours they worked. It's crazy that Congress plays political games with essential services like ATC.
Utterly unqualified to suggest any causes (wait for the NTSB report on that), but couple compounding factors I've read elsewhere to begin to understand the situation and context:
- Another plane was out of position, grabbing some attention of the controller
- Stop communication was ambiguous about whether talking to previous plane or firetruck
- The colliding plane didn't have "explicit" landing clearance, but a "follow previous plane and land the same way unless told otherwise" implicit landing clearance. In Europe, planes need an explicit landing clearance, the act of granting it may have brought attention to the runway contention. US implicit system (arguably) is a bit more efficient, debate will now be is it worth it (pilots are now required to read back instructions because of past blood... will this result in same thing?)
- This was around midnight and apparently a little foggy, making visual contacts harder
Remember folks, disasters like this are rarely caused by a single factor. NTSB reports are excellent post-mortems that look at all contributing factors and analyze how they compounded into failure. Be human here.
Emergency vehicles were en route to another emergency in progress on the other runway. Sadly it sounds like a fire truck was cleared to cross the active runway moments before the CRJ landed. By the time the controller realized that mistake it was too late.
I'm very, very curious about whether the ARFF crew visually cleared the runway and final before crossing the hold short line. It's standard procedure for flight crew to do this, specifically to mitigate the risk of ATC errors.
Reports are there were fog and rain at La Guardia at the time of the incident. They were on a short final, and it’s entirely possible they were not visible to the fire truck’s crew.
Yes ARFF should still look before crossing, but the weather wasn’t great with limited visibility and thus even if they looked it’s possible they didn’t see anything.
Was curious if ground vehicles at airports also use transponders to communicate position to the radio tower, and it turns out the FAA put out a report last year on potential solutions to avoid this exact situation:
The only negative I can think of is that it will generally involve accepting and responding to clearances on short final. I think adding more tasks to that critical stage of flight probably increases danger a little. Especially for low time student pilots like myself. That's particularly relevant in the U.S. because we have a higher percentage of student and private pilots than most of the world.
Overall, though, I'm fully convinced this would be safer.
Transponder doesn't alter the laws of physics for the landing plane you just cut off. I guess it gives ATC a ~5sec jump on telling some other flight to go around.
I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
> I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
I highly doubt that any system would intentionally give ground vehicles of any kind special treatment on an active runway.
> Captain and first officer are reported to have died in the accident, two fire fighters on board of the truck received serious injuries, 13 passengers received injuries.
The shortage of ATC staff dates back to the Clinton Administration. It’s just hard to attract people into a 5+ year training program for a very stressful job where you might get bounced near the end with no payout and no transferrable job skills.
No the shortage goes back to Regan when their justified strike was busted. It ended the PATCO “union” and was a negative turning point for labour unions in general.
I think you mean Reagan. He removed the union for the ATC not Clinton.
Honestly, you can generally just blame Reagan for about anything. A presidency about weaking labor, strengthening Iran, and ballooning the deficit is uh never going to leave good traces.
Reagan did the right thing in that case. Government employees should never have collective bargaining rights. Public employee unions are contrary to the interests of taxpayers.
Over the course of the past year, I think we've seen more evidence that the federal workforce's collective bargaining rights aren't strong enough. Workers' employment contracts are being ignored, employees are being threatened, constructively terminated, all in an attempt to enact RIFs without following the law.
Things are happening to the federal workforce right now that aren't even legal in the private sector.
Yes, absolutely. No government employees should ever have collective bargaining rights. If they want better wages and working conditions then they can advocate for those through the political process, the same as any other citizen.
ATC/GTC seems like a really strong candidate for partial automation with recent advances in AI. Obviously we'd still want some expert humans in the loop for exceptional situations, but I have to imagine there's a way to significantly reduce the cognitive burden/stress for these folks.
Recent advances in AI aren't useful for routine operations in safety critical domains such as aviation because we don't know how to verify and test them. An LLM is effectively an unpredictable black box with unknown failure modes. There is opportunity for greater automation but probably based on classical deterministic programming.
Yup, it's been a problem ever since Regan (a Republican) fired over 11,000 ATC employees. And by "anyone" ITYM "republicans" again, because Democrats have been trying for years.
I'm curious about what kind of visualization does the ATC have at the disposal about the current occupancy of the individual tarmac segments? I'd assume if an airplane is approaching for landing on a specific runway, that runway should have been clearly marked as restricted for access until the plane would actually land and clear it?
In the US, airplanes can be cleared for landing while the runway is occupied (you can be number two, three, etc. for landing and still be cleared). It's different in other countries, where you can only be issued a landing clearance if the runway is clear or anticipated to be clear before you land (e.g. the plane before you is already exiting the runway).
The way it's supposed to work, the ground controller first verifies that there are no traffic conflicts before clearing vehicles to cross an active runway.
The fire truck was flipped and moved to the side of the runway, this was not 24mph. 24mph is the final groundspeed recorded after the aircraft skidded off of the runway.
Per the ADSBx track the plane was at 101kts (115 mph / 185kph) just before crossing taxiway D, which would be where it hit the firetruck. It still had enough energy afterwards to reach taxiway E, 600ft away.
The results seem on the high end but they check out at first glance.
A plane is basically a flimsy tube. A firetruck is a solid brick comparatively. The plane out weighs the fire truck by a lot and out speeds it by a lot. So yeah, destroying the whole front of the plane to punt the truck it sounds about right for a 25 on 5 or 35 on 10/15 type rear ending to me. Flipping doesn't really sound that unreasonable considering that the plane made contact with the top of the truck (just by virtue of comparative height) and contact may not have been straight on. Even if it left the pavement on it's wheels airport firefighters aren't exactly who I'd bet on (they're middle of the pack) to keep the truck on it's wheels if they got surprise kicked off the road especially if there's an embankment involved.
Pause the video at 13 sec. That firetruck is awfully intact for something that allegedly got hit at high speed. Basically just a bunch of top side sheetmetal damage (concentrated to the rear, obviously). In any case it didn't even get sent hard enough to screw up the cab exterior. And on the flip side, if you keep cranking the speed up you start getting to where the plane starts looking too suspiciously intact. There's just not much room to work backwards from the apparent results and get a high difference in speed or get very high initial speeds (100 onto 75 or whatever). If the plane was going fast the truck had to be going fast too or there'd be more carnage. But if they were both going fast you'd expect more damage from the after the fact barrel roll and the plane and truck to be a little farther apart in distance.
The back of a firetruck is not a working implement like a dump truck is nor is it sufficiently strong for mounting a crane or man bucket like utility bodies often are It's a bunch of sheetmetal boxes to hold stuff and cover stuff and there's a water tank back there somewhere. In the middle down low some pumps are buried. Basically don't think of it as being any more structural than a box truck body because it's not. All that stuff got shredded, obviously, since they're only really meant to bear their own weight and were subject to all the truck tossing forces here. Beyond that the truck is in pretty good shape. It's not uncommon for a good "off the highway and into the ditch" crash to rip tandems off, twist frames, etc. None of that has happened here. The plane is pretty rough, but that's expected. They are 100% tin cans. Ground equipment moving at idle speeds will absolutely shred them before the operator even feels resistance. A goose hit square on the leading edge of a small jet's wing will put a massive dent in (and apply red paint, lol).
24 sounds about right for a closing speed for plane onto truck. Whatever the baseline speed of the truck was cannot have been that high or the truck would be absolutely shredded from the barrel roll and as it stand the cab is barely pushed in.
The last recorded ground speed data of 24mph also shows a wildly different heading (going from 30deg ish to 170ish). So it probably happened after the collision and was part of its deceleration. As far as I know, the truck would have been crossing the runway so the effective speed perpendicular to the plane would be zero except for directional shear I guess.
The speed was much higher per sibling comment, but also remember that kinetic energy also involves mass (planes are heavy) and the square of the velocity.
It looks like that is based on the last recorded speed from flightradar24[1] which was 21kts(24mph). The previous data points were 11kts, and 58 kts(the last point before the track deviates off the runway). I do think it is likely that the collision occurred at a speed faster than 24mph.
edit: Looking into this a bit more it looks like the plane came to a stop around crossing E while the emergency vehicle was crossing at D(based on ATC recordings). Using the following map as reference[2], the 58kts point was around E, while the previous recorded point which was just before D was 114kts.
On other hand planes are really not designed to be crashed into things. Only for limited impacts. So we might not have right comparison for relatively thin and aimed to be light structure being impacted by bulkier object.
Speed doesn't cause damage. Momentum causes damage. We understand speed, we do not understand momentum. It makes sense given our evolution.
People into boats need to understand this. Even a boat that travels no more than 4mph can crush you easily. This is why you never get on to moving boat from the front. Many people have made a mistake because speed is not high.
Tugboats bump other boats all day. Hundred thousand pound pieces of machinery bury themselves into the dirt. All this as part of normal operation. It's not that simple.
Speed, kinetic energy and acceleration are all interrelated and at the end of the day it's all forces (to some extent) and no amount of hand wringing commentary is going to replace genuine understanding of them.
Gravity. The aircraft is heavier at the back, where the engines are. With the nose severely damaged/missing, the centre of gravity has shifted aft, so what’s left of the nose is sticking up in the air.
I’d guess the front landing gear assembly is going to be fairly heavy, and appears to be missing. This model of plane also has its engines at the rear, not under the wing, which will move the balance to the back.
Planes typically have their center of gravity just forward of the rear wheels. This makes it easier to rotate on takeoff.
The margins are thin enough that certain planes will sometimes have people in the back get off first, before the people on the front, to avoid tipping onto the tail like this.
Are the increased number of air incidents since Dec 2024 reflective of anything real or is it more attention on something? Brigida v. USDOT comes to mind but doesn't seem relevant. I'm sure we could all construct a chain of "this thing happened that caused that which caused this" and so on, but I'm curious if someone has done the effort to see whether such a chain is defensible.
Also, did the pilots die in the collision or in some sort of aftermath? The cockpit looks absolutely smashed.
You can probably construct a realistic chain of failure that goes all the way back to political tomfoolery and bad air traffic control leadership/staffing decisions, but that makes the wrong people look bad, so they'll probably blame individuals further down the totem pole like the controller or pilot and call it a day.
The entire cockpit, front toilet and galley area, and probably a front row seat have all been utterly destroyed. Unfortunately I'd be amazed if the death toll stays at two.
It should be noted that aircraft and all other vehicle and personel movements on an airport are controlled from the airtraffic control tower by air traffic controllers or
directly by individual flaggers, as directed from the tower.
Or at least thats the way it is supposed to work, and of course the operation at a place like LaGuardia is more complex, and will have specialists and multiple zones.
What will put an extra edge on this is the
whole ICE thing, and airport chaos pulling the roof down.
> What will put an extra edge on this is the whole ICE thing, and airport chaos pulling the roof down.
How would the ICE thing cause more ground traffic collisions. Are you thinking ATC controllers are illegal immigrants and they’re going to run away during their shift? I just don’t see a connection there…
This incident caused delays and cancellations that ripple throughout an already understaffed network of TSA checkpoints. ICE presence will make airport security somehow an even worse experience for brown people.
Not the crash, but the aftermath. Passengers will be showing up for flights today, nervous with the crash on their minds, and many will then encounter untrained goons cosplaying as airport security.
This comes to mind how during the Boeing news scandals, commenters would confidently argue "Flying is still ridiculously safe, statistically speaking", "these things happen every day, just underreported", and "you/people are irrational for not flying Boeing". It's a very curious argument to me. Is the ATC infrastructure issue analogous or not, etc.
Maybe US media, hardly an unbiased news source about US events, especially when hundreds of billions are flying around about incompetent massive employer and lobbyist.
Nowhere else in the world you would hear such statements. Boeings simply disappeared from Europe, those few that were here before. I am sure they are still used somewhere but I haven't flown any in past 7-8 years. Heck, I haven't seen any in South east Asia neither (but that may be due to luck).
I check this with all bookings, no way I am flying that piece of shit if I can anyhow avoid that, not alone and quadruple that with family.
It is strange. What is importa t is, are things getting better or getting worse? As they say, it’s not the fall that kills, bit the impact. Are we falling?
/r/xyz doesnt need to fact check. Sure those are excellent subs but just being watering holes and not legal entities they can move faster. There were some wrong facts on r/aviation although it got viral so people just ploughed in with whatever news outlet they read it on.
The clearance for AC8646 to land on runway 4 is given in a sequence starting at 4:58. "Vehicle needs to cross the runway" at 6:43. Truck 1 and company asks for clearance to cross 4 at 6:53. Clearance is granted at 7:00. Then ATC asks both a Frontier and Truck 1 to stop, voice is hurried and it's confusing.
If only we could diff the BBC article (it currently says it was posted 21 mins ago which is younger than your comment…). It’s changed multiple times now without any kind of changelog or acknowledgement.
> Video footage on social media showed the aircraft, which is operated by Air Canada's regional partner Jazz aviation, coming to a rest with its nose upturned.
This just isn’t true. There’s no video of the plane coming to a rest with its nose upturned (which implies motion). The upturned nose happened only after passengers deplaned and the balance shifted.
> It had slowed to about 24mph when it collided with a vehicle from the Port Authority of New York and New Jersey, which runs the airport.
This is the next part that will change. Just because some of the last broadcast data said 24mph doesn’t mean that’s the speed it was when it collided with the truck. The truck is on its side and those passengers are in hospital. The pilots are dead. The plane sustained enough structural damage to have the entire nose collapse. If the sentence is based on that broadcast data, SAY THAT instead of printing it as fact.
And with all the quotes from social media posts from key groups, link to them instead of just vaguely quoting.
EDIT:
As expected, they got rid of the above paragraph claiming the speed. It now says:
“The plane was arriving from Montreal and had landed, before colliding with the vehicle from the Port Authority of New York and New Jersey, which runs the airport.”
Any of us can help log the changes by submitting revisions of the article to web.archive.org
With a fast-changing news story where vague/incomplete/conflicting details emerge in the first few hours it's not unreasonable for the first few revisions to be like that, and eventually gets fixed hours or a day later.
I think that’s what’s critical here. Post details and their sources to show that they are in flux. Don't write them as fact and then make secret edits.
Because some of them still have standards. They will correct themselves if something was wrong.
Everyone can write a comment on Reddit / make a podcast / video / whatever claiming whatever they want. Unless you already know and trust them (which requires you to be able to cross-check their information), it's potentially as useful as a random LLM hallucination. Could be brilliantly spot on, or could be completely nonsense. No way of knowing unless you already know enough. (Because even cross-checking won't necessarily save you, if you cross-check multiple bullshit sources).
Media with standards (like the BBC, Guardian, Liberation, etc.) will do their best to report truthfully (even if sometimes with some bias), and will fix their mistakes if they're caught later on or the story evolves. Independent media checking organisations have shown time and time again that there is trustworthy media, you just need to know which it is, and always take a pinch of salt. It's wild to me that people will just dismiss rags such as Fox News and relatively quality media like Guardian in the same breath.
In 2026, with how much money their is in aviation, it seems wild to not have digitized this ages ago. The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
That ATC still takes place over radio just seems insane at this point. And there's pretty much no way to make ATC's job not stressful, its inherently stressful. Taking out how much of their job is held in the current operators mind versus being 'committed' seems like low hanging fruit 30 years ago.
The whole system's just begging for human error to occur. There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
Air traffic (and ground traffic) control are not simple problems. La Guardia has 350k aircraft operations (takeoffs and landings) every year. 1000/day. Peak traffic is almost certainly more than 1 plane every minute. Runways are always in use and the idea that some simple software will solve all the safety problems is not grounded in reality.
Software routinely solves database coordination problems with millions of users per second.
No one said it was simple. You're tilting at windmills.
Literally called it “low hanging fruit”.

One jet landing every minute, coordinating the airspace for miles around the airport, along with coordinating non-landing traffic (helicopters, small craft), while making sure these (already heavily automated) flight systems dont get confused and kill several hundred people sounds easy to you, along with keeping everything on time and schedule?
Go write it then.
And I think most critically: being able to adapt all of this on the fly when invariably something goes off-plan.
Aviation is over 100 years old. Everything that can possibly happen in ATC has either already happened or can reasonably be anticipated.
It's stupid, wasteful, and ultimately dangerous to make a human do a machine's job.
You say it “…sounds like a simple problem,” and sure, if you think this is a computer problem, it sounds simple. But if all you’re getting back is indignant sputtering, that’s your cue to explain why it’s simple—explaining something simple shouldn't be hard. What do you actually know?
It takes all of two minutes of Wikipedia reading for me to understand why this isn’t simple; why it's actually extremely not simple! If you ignore the incumbency, the regulations, the training requirements, the retrofitting, the verification, the international coordination, and the existing unfathomably reliable systems built out of past tragedies, then sure, it’s "simple". But then, if you're ignoring those things, you’re not really solving the problem, are you?
while making sure these (already heavily automated) flight systems dont get confused and kill several hundred people
Confusion is indeed a common side effect of a job done halfway.
Replying: I'm really confused at the point you're trying to make - you declared yourself not an expert in this field, while loudly declaring it's so easy to automate.
Because we've already done harder things. 1000 takeoffs and landings per day equals a trillion machine cycles between events... on the phone in your pocket. It is an extraordinary claim, requiring extraordinary proof, to say that this task isn't suitable for automation.
Why don't you do it then? What am I missing?
I'm not qualified to do it, I didn't say I was, and in any event, I don't work for free. I'm asking for concrete reasons why it's not feasible. Spoiler: there are no reasons, only excuses.
> I'm asking for concrete reasons why it's not feasible. Spoiler: there are no reasons, only excuses.
It sounds like you're not asking anything at all
Just to play it out a bit, are you imagining that a pilot would be reporting a mechanical failure upon descent into busy airspace to some type of like AI voice agent, who will then orchestrate other aircraft out of the way (and not into each other) while also coaching the crippled aircraft out of the sky?
Are you imagining some vast simplification that obviates the need for such capability? Because that doesn't seem simple at all to me.
I'm really confused at the point you're trying to make - you declared yourself not an expert in this field, while loudly declaring it's so easy to automate. Why don't you do it then? What am I missing?
> Why don't you do it then? What am I missing?
I know this was rhetorical but the obvious answer is a complete lack of any actual ideas. “Just automate it” is a common refrain from people who don’t know how to fix the actual issues with any domain.
Remember how we installed traffic lights all over the roads and now car crashes never happen any more at intersections? Truly automation solves all problems.
> Every time I've asked what's so hard about automating ATC
Why don’t you describe the hypothetical automation you believe would solve the problems then?
My hunch is that either your ideas are already implemented (like GP post who said they need to add red lights at the runway instances, except yeah, they do have that), or they are just bad.
> indignant sputtering and patronizing hand-waving.
Preemptively insulting everyone who might respond to you certainly looks like you’re asking for a real conversation. :|
Your accusation of “patronizing hand-waving” is especially off base considering you literally proposed nothing except “automating”. Hand waving indeed.
I worked in aviation in the late 1990s and automating ATC is all they could talk about. So, that's almost 30 years of talking and no action.
That's because it's a political problem, and not a technical problem. It could have been done then, and it can be done now.
Just curious: how many people in this thread know what SAGE was? A $5 Arduino has more computing power than the whole SAGE network.
> The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
It does, the Runway Status Lights System uses radar to identify when the runway is in use and shows a solid bright red bar at every entrance to the runway. I'm curious what the NTSB has to say about it for this incident. From the charts LGA does have RWSLs. I didn't check NOTAM to see if they were out of service though.
Emergency vehicles almost always can override/ignore warning devices (think firetrucks running red lights) which can cause "fun" for some value of "death/dismemberment/vehicle loss".

> That ATC still takes place over radio just seems insane at this point.
Voice communication is insane? I suspect you are ignorant of what it is like to actually fly a large aircraft into a busy airport. Fault-tolerant and highly available hardware must facilitate low-latency, single-threaded communication with high semantic density in order to achieve multi-dimensional consensus in a safety-critical, heterogeneous, adversarial environment.
There is some interesting research that captures this sentiment and shows how complex a solution might need to be (replace "faulty agent" with "human error"): https://www.sciencedirect.com/science/article/abs/pii/S00051...
How would you exactly "digitize"? While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
> While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
Traffic lights instead of mad max intersections are better.
Then there's subway Automatic Train Control.
I don't know that Air Traffic Control staff don't have computer systems for establishing which plane owns what airspace. They at least did do it manually already following specific processes, so it can be at least augmented and a computer can check for conflicts automatically (if it isn't already). And, sure, ATC could still use radio, but there could be a digital standard for ensuring everybody has access to all local airspace data. Or maybe that wouldn't help.
Your ground vehicle wanting to cross a runway could have the driver punch "cross runway 5" button (cross-referenced with GPS) and try to grab an immediate 30 second mutex on it. The computer can check that the runway is not allocated in that time (i.e. it could be allocated 2 minutes in the future, and that would be fine).
But, as pointed out elsewhere, obviously some of this is already present: stop lights are supposed to be present at this intersection.
The Runway Status Light system already does this via automated monitoring of traffic from multiple systems: https://www.faa.gov/air_traffic/technology/rwsl
I'm sure the NTSB report will cover why this didn't stop the accident. Presumably either the system wasn't working as-expected, or the fire truck proceeded despite the warning lights since they had clearance from the controller.
The system is only advisory at present, so if the truck did see a warning light and proceeded anyway, they were technically permitted to do so.
>In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
1700 incursions a year, and other articles mentioning multiple near misses a week at a single airport [1]. It is safe in practice, likely largely due to the pilots here also being heavily trained and looking for mistakes, but it seems a lot like rolling the dice for a bad day.
>I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
I didn't say it'd be free. Just hard to believe radio voice communication is the best way to go.

The problem with the analogy is that aviation has no equivalent to "maintain a safe following distance" or "pull over and come to a stop". If a plane is on an active runway, or in flight, it's generally compelled by physics to keep moving forward one way or another. An automated system that prevented the truck from entering the runway would have been great, but an automated system that falsely reported a truck on the runway might have caused a disaster by forcing the plane into dangerous maneuvers to avoid it.
Lmao the one hope I have for this country is that I know for sure that the American people will rise up to put a violent end to techbros once they try to “ ban non self driving cars”
And I suppose people flying an 40 year old Cessna 172 will share the same feeling if someone wants to "digitize" it.
There is a ton of tech in airplanes we don't require in every car, your 'argument' here is nothing more than strawman I refuse to entertain.
What tech do you suppose we’d put in an airplane that would stop a fire truck from driving onto the runway? Gatling guns?
The BBB allocated $12B for ATC modernization. https://www.faa.gov/new-atcs
Money isn't the only reason it's so old. The coordination problems are huge. https://www.theregister.com/2024/09/24/us_air_traffic_contro...
> There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
How many runways crossings are there in a year? How much is "1700+" a percentage of that total?
The point is that it doesn't matter what percentage of the total they are, it's that 1 is too high without adequate explanation (the Gimli Glider caused vehicles to be guilty of a runway incursion by turning an abandoned runway into an active one, for example).
And the cost of investigating 1,700 should be within the budget.
My very fuzzy back of the envelope says easily 10s of thousands per day.
ATC recording on https://www.liveatc.net/recordings.php Fire truck was cleared to cross and then told to stop. I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller.
They were indeed the only controller, working both ground and tower frequencies.
Which, as a non informed person but someone who needs to travel by plane, sounds absolutely insane. Was it always possible to staff that with a single person or is that a result of understaffing?
As an informed person (PPL flying single engine into smallish towered airports all the time), it is absolutely insane for an airport the size of LGA. Occasionally, you will encounter one guy doing tower and ground at very small class D airports or during not-so-busy shifts.
To play devil's advocate, ASEL into small deltas is significantly different than receiving full-stop IFRs late at night.
This small mistake (and it is initially small, just catastrophic) is a system breakdown, not necessarily a staffing breakdown. Though staffing is definitely a wider issue in the NAS.
I fly out of a small-to-medium-sized airport in Canada and I've never seen it happen. The idea of one person being responsible for both tower and ground in the busiest airspace in the US is absolute insanity.
That seems unusual to me. It’s common at smaller airports, but for a big one like LaGuardia I’d think tower and ground would be two different controllers, even lateish at night like this was. I know there has been a staffing problem for controllers in the NY area for some time.
It's absolutely understaffing.
But think of the money they saved by not having to pay another air traffic controller! A controller's yearly salary is the cost of about 10 seconds of the Iran war, based on the recently-reported figure of $11.3B for six days.
[flagged]
New York State is large. It has lots of airports [0] - although not all of those are towered, you're still dividing that 260 down by quite a lot. And I don't believe it's standard practice to fly some dude in Buffalo down to NYC to cover a shift. There's a huge staffing problem in ATC right now.
That staffing problem mostly comes down to it being demanding work that's poorly compensated for the amount of skill and education and stress involved; there are high hiring standards, you can't work past 56, and you can't even get started if you're past 31. If you're interested in aviation, you can make far more money as a pilot and it's a much more pleasant job; why would anyone become an ATC?
[0] https://en.wikipedia.org/wiki/List_of_airports_in_New_York_(...
>you're still dividing that 260 down by quite a lot
No you're not.
In the state of New York, the most it could possibly be divided down is by 32.
And that only in the case that ATC are distributed to towered facilities equally whether commercial or simple public-use. Which we both know they are not.
And I'll do you a really big favor and not even mention the fact that there are wayyy more than 260 ATC in New York state. Again, I was just being friendly to your view. I strongly suspect that you are also aware that there are well over 1000.
260/32 is around 8. "A lot" is subjective but I think that fits the bill?
LGA is open 16 hours a day, seven days a week. Of course this is an extreme over-simplification, but if LGA only had eight ATC at their disposal total it's easy to see - or at least, much easier to see than if your working number is 260 - how they might have only one guy available to work Tower/Ground on a night shift. Please bear in mind that there's more to ATC in an airspace like NYC's than just Tower/Ground, and that ATC need regular breaks. Maybe they had two people but no redundancy, so one guy was covering both tasks during a break?
Are you under the impression that air traffic controllers only work at towers in commercial airports?
Your math is based on incorrect assumptions -- the well-documented ATC shortage actually exists.
Do you know how many towered facilities there are in New York state?
32.
Let's assume only 260 ATC for 32 towers. (Not true, but again, we're being friendly to the conspiracy nuts.) We'll further assume every tower is staffed equally. (Also not true, but again, friendly to the nuts.)
8 Controllers for each tower if those assumptions were true. Which they are not.
Why is one controller on duty in a commercial airport? Not a public-use airport, a commercial airport?
Please stop with the BS.
And for my next question: are you under the impression that air traffic controllers only work at towers?
The problem is that you're comparing numbers from before Trump's presidency, but the understaffing of FAA ATCs goes all the way back to when the Reagan administration fired all ATCs to break up the union and forbade the FAA from rehiring any former union members.
The FAA has been playing catch up with training enough ATCs to meet demand ever since, which isn't helped by a sequence of bad decisions made regarding ATC training schools.
[flagged]
This sounds like a right-wing conspiracy theory. Are you saying that, in order to hire more black people, the FAA deliberately created a test only black people could pass? Do you have any evidence of this assertion?
Unfortunately, it is not a conspiracy theory, right wing or otherwise.
Lots of people have written about it, here’s a few:
https://www.tracingwoodgrains.com/p/the-full-story-of-the-fa...
https://simpleflying.com/faa-air-traffic-controller-applican...
https://www.blockedandreported.org/p/premium-the-faas-bizarr...
https://www.newsweek.com/faa-reject-air-traffic-controllers-...
https://highsierrapilots.club/faa-hiring-scandal/
The only domain I recognize is Newsweek, and given the nature of astroturfing, I’m not going to trust domains I don’t recognize.
All the Newsweek article says is that a lawsuit was filed. It doesn’t support GP’s claim that the FAA made “an impossible test, and gave black people the answers.” A lawsuit isn’t evidence of wrongdoing; it’s only evidence of an accusation of wrongdoing.
Worth noting that Newsweek went out of business over a decade ago and their domain and branding was bought by a cult and used to run an SEO business.
You're correct to be suspicious.
Looking at the front page of 2 of those domains ( tracingwoodgrains, blockedandreported ) they are ... ah .. not exactly impartial. Sample headlines: "How Wikipedia Whitewashes Mao - The Anatomy of Ideological Capture" and "The Politics of Misery - Why are young liberals so depressed".
The simpleflying link gives the name of the person filing the lawsuit as this character: https://en.wikipedia.org/wiki/Adam_Laxalt who is also ... not exactly impartial, seeing as he "was the Republican party nominee for governor of Nevada in the 2018 election". And as other searches suggest, no stranger to frivolous litigation or false claims.
In summary, spending 5 minutes digging into it gives every impression of it being culture war nonsense.
I don't think this explains understaffing though.
"The lawsuit doesn’t allege incompetent controllers were hired instead of CTI graduates. Instead, it states that the CTI graduates weren’t given the opportunity to demonstrate their competency."
It sounds like they hired different people, rather than fewer.
Not a pilot or a controller, just a nerd. My take from reading about it was that a large number of high performing potential ATC controllers who had followed the traditional pipeline were ditched. Ofc it's possible they hired exactly as many ppl as they would have otherwise, but in any job with a long lead time for training, a sudden change in the pipeline is going to cause ripples further on for years to come. Maybe the ppl they did hire had a higher attrition rate so that while they had the same # of ppl in the short term, in the long term, they faced shortages. Maybe some % of those they did hire required some % of extra supervision or training. Ofc not insurmountable or fatal, it just means extra pressure that will exert itself in some fashion for years to come after the initial disruption. I have no idea of last night's incident could be considered downstream of the testing change, I was just responding to the allegation that it was a conspiracy theory, however I also don't think it's implausible that it contributed to it in some indirect way.
Maybe the ppl they hired had a lower attrition rate! Maybe the people hired required less supervision and training than the CTI graduates would have! Maybe this had rippling effects on increasing their hiring pipeline as people of color were more likely to see opportunities here.
Your comment presuming it was at best neutral, and any likely change was for the worse is exactly what racism looks like.
Except they had a much higher attrition rate because ATC is a terrible job.
> I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller
I remember late last year, couple of months ago, US ATC controllers were without pay but forced to work anyways (similar to TSA I suppose, although I don't think they were forced, but volunteered to work without salary), is that still the situation? Couldn't find any updates about that the situation been resolved, nor any updates that it's ongoing, if so though it feels like it'd be related to the amount of available controllers.
The US has had trouble keeping enough controllers. It's a skilled but extremely stressful job, and so retention would always be difficult but the US also works hard to make it suck more than it should, and of course the over-work from not having enough people makes that even worse.
But no, AIUI only things that were somehow deemed part of "Homeland Security" are frozen, the TSA are part of Homeland Security but the ATC are under the FAA. So this particular partial government funding lapse wasn't causal, at least directly.
ATCs weren't exactly forced to work: they aren't slaves and are free to quit any time. But if they didn't show up for assigned shifts even though they weren't getting paid then they were subject to disciplinary action including termination. Some of them called in sick, or took on temporary second jobs to bring in some cash (obviously a bad thing from a fatigue management standpoint). After the government shutdown they were paid in arrears for all of the hours they worked. It's crazy that Congress plays political games with essential services like ATC.
Utterly unqualified to suggest any causes (wait for the NTSB report on that), but couple compounding factors I've read elsewhere to begin to understand the situation and context:
- Another plane was out of position, grabbing some attention of the controller
- Stop communication was ambiguous about whether talking to previous plane or firetruck
- The colliding plane didn't have "explicit" landing clearance, but a "follow previous plane and land the same way unless told otherwise" implicit landing clearance. In Europe, planes need an explicit landing clearance, the act of granting it may have brought attention to the runway contention. US implicit system (arguably) is a bit more efficient, debate will now be is it worth it (pilots are now required to read back instructions because of past blood... will this result in same thing?)
- This was around midnight and apparently a little foggy, making visual contacts harder
Remember folks, disasters like this are rarely caused by a single factor. NTSB reports are excellent post-mortems that look at all contributing factors and analyze how they compounded into failure. Be human here.
In the USA at controlled airports, aircraft also need explicit landing clearance.
"Jazz 646, number 2, cleared to land 4."
https://youtu.be/Pbm-QJAAzNY?si=h3VEuVNLMf9Z8D1c&t=126
I’m always staggered by how stressed and tbh (not necessarily their fault given the circumstances) unprofessional US ATCs sound.
Sharp contrast with Europeans
Emergency vehicles were en route to another emergency in progress on the other runway. Sadly it sounds like a fire truck was cleared to cross the active runway moments before the CRJ landed. By the time the controller realized that mistake it was too late.
I'm very, very curious about whether the ARFF crew visually cleared the runway and final before crossing the hold short line. It's standard procedure for flight crew to do this, specifically to mitigate the risk of ATC errors.
Reports are there were fog and rain at La Guardia at the time of the incident. They were on a short final, and it’s entirely possible they were not visible to the fire truck’s crew.
At night with multiple runways it can be very hard to see a plane on final.
Still, I'm always hesitant to cross an active runway.
Yes ARFF should still look before crossing, but the weather wasn’t great with limited visibility and thus even if they looked it’s possible they didn’t see anything.
I mean, isn't it obvious that they didn't?
It’s obvious that either they didn’t, or they did but they didn’t see the plane. We don’t know which.
Was curious if ground vehicles at airports also use transponders to communicate position to the radio tower, and it turns out the FAA put out a report last year on potential solutions to avoid this exact situation:
https://www.faa.gov/airports/airport_safety/certalerts/part_...
Many airports have ADS-B transponders in their ground vehicles. You can see them on flightradar or adsbexchange.
> Was curious if ground vehicles at airports also use transponders to communicate position […]
They do at CYYZ (Toronto Pearson):
* https://www.flightradar24.com/43.68,-79.63/13 (zoomed in)

Also at CYUL (Montreal Trudeau) and CYVR (Vancouver International).
Ground vehicles with transponders: https://adsb.exposed/?dataset=Planes&zoom=7&lat=42.1262&lng=...
Or just do like the rest of the world. No anticipated clearences to land, you only ever get a clerance when the runway is empty and yours.
I think this is a good idea.
The only negative I can think of is that it will generally involve accepting and responding to clearances on short final. I think adding more tasks to that critical stage of flight probably increases danger a little. Especially for low time student pilots like myself. That's particularly relevant in the U.S. because we have a higher percentage of student and private pilots than most of the world.
Overall, though, I'm fully convinced this would be safer.
Even without anticipated clearance to land you have to define what "the runway is empty and yours" means.
Yeah that gut wrenched ATC had to stay on point and ensure the next plane to land did a go around. Scary stuff.
Us lot have more people doing SRE ensuring p99 10ms for something frankly way less important. It is a nuts world.
LaGuardia has that system, it still failed to prevent this
Transponder doesn't alter the laws of physics for the landing plane you just cut off. I guess it gives ATC a ~5sec jump on telling some other flight to go around.
I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
> I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
I highly doubt that any system would intentionally give ground vehicles of any kind special treatment on an active runway.

make a mistake, recognize it, and then have to continue on your job, knowing you likely just killed people, because if you don't others will die.
The weight of some jobs is immense, and our civilization relies upon workers to shoulder the burden everyday.
And these guys are tremendously overworked because the government can’t get its shit together to hire enough people to staff at appropriate levels.
"Government"? Let's call it what it is. ITYM "Republicans".
The shortage of ATC staff dates back to the Clinton Administration. It’s just hard to attract people into a 5+ year training program for a very stressful job where you might get bounced near the end with no payout and no transferrable job skills.
No the shortage goes back to Regan when their justified strike was busted. It ended the PATCO “union” and was a negative turning point for labour unions in general.
I think you mean Reagan. He removed the union for the ATC not Clinton.
Honestly, you can generally just blame Reagan for about anything. A presidency about weaking labor, strengthening Iran, and ballooning the deficit is uh never going to leave good traces.
Reagan did the right thing in that case. Government employees should never have collective bargaining rights. Public employee unions are contrary to the interests of taxpayers.
Over the course of the past year, I think we've seen more evidence that the federal workforce's collective bargaining rights aren't strong enough. Workers' employment contracts are being ignored, employees are being threatened, constructively terminated, all in an attempt to enact RIFs without following the law.
Things are happening to the federal workforce right now that aren't even legal in the private sector.
Does your comment also include the police union(s)?
Yes absolutely. They're a perfect example of the unique issues w/ collective bargaining for public services.
Yes, absolutely. No government employees should ever have collective bargaining rights. If they want better wages and working conditions then they can advocate for those through the political process, the same as any other citizen.
ATC/GTC seems like a really strong candidate for partial automation with recent advances in AI. Obviously we'd still want some expert humans in the loop for exceptional situations, but I have to imagine there's a way to significantly reduce the cognitive burden/stress for these folks.
Recent advances in AI aren't useful for routine operations in safety critical domains such as aviation because we don't know how to verify and test them. An LLM is effectively an unpredictable black box with unknown failure modes. There is opportunity for greater automation but probably based on classical deterministic programming.
Yes. Reagan was a Republican.
No, I mean government. This has been a problem for a long time and there hasn't been any serious effort to improve the situation by anyone.
Yup, it's been a problem ever since Regan (a Republican) fired over 11,000 ATC employees. And by "anyone" ITYM "republicans" again, because Democrats have been trying for years.
See this article from 2017: https://www.govexec.com/oversight/2017/06/house-democrats-in...
I'm curious about what kind of visualization does the ATC have at the disposal about the current occupancy of the individual tarmac segments? I'd assume if an airplane is approaching for landing on a specific runway, that runway should have been clearly marked as restricted for access until the plane would actually land and clear it?
In the US, airplanes can be cleared for landing while the runway is occupied (you can be number two, three, etc. for landing and still be cleared). It's different in other countries, where you can only be issued a landing clearance if the runway is clear or anticipated to be clear before you land (e.g. the plane before you is already exiting the runway).
Still, the runway could be reserved for landing aircrafts only, still preventing access to all other types of vehicles.
How are fire trucks supposed to respond to incidents involving airplanes, as it appears this case involves, if the runway is off limits to them?
The way it's supposed to work, the ground controller first verifies that there are no traffic conflicts before clearing vehicles to cross an active runway.
Which is exactly what failed here, so saying "it shouldn't fail by not failing" doesn't help terribly much.
Having grade-separate crossings for vehicles might, but that introduces new issues (plane skidding off runway could hit the incline and break up).
That's a huge amount of damage even at 24mph. It's crazy how that could happen though. Will be interesting to see the full report.
The fire truck was flipped and moved to the side of the runway, this was not 24mph. 24mph is the final groundspeed recorded after the aircraft skidded off of the runway.
Per the ADSBx track the plane was at 101kts (115 mph / 185kph) just before crossing taxiway D, which would be where it hit the firetruck. It still had enough energy afterwards to reach taxiway E, 600ft away.
Okay that makes far more sense the article didn’t really make that clear to me.
The results seem on the high end but they check out at first glance.
A plane is basically a flimsy tube. A firetruck is a solid brick comparatively. The plane out weighs the fire truck by a lot and out speeds it by a lot. So yeah, destroying the whole front of the plane to punt the truck it sounds about right for a 25 on 5 or 35 on 10/15 type rear ending to me. Flipping doesn't really sound that unreasonable considering that the plane made contact with the top of the truck (just by virtue of comparative height) and contact may not have been straight on. Even if it left the pavement on it's wheels airport firefighters aren't exactly who I'd bet on (they're middle of the pack) to keep the truck on it's wheels if they got surprise kicked off the road especially if there's an embankment involved.
A CRJ 9000 is 70000 lbs empty, 84500 lbs MTOW.
An Oshkosh 1500 4x4 is 62000 lbs GVWR (wiki says kerb weight but it’s incorrect).
The plane was landing and the truck was heading to an intervention, so they were likely close to empty and to GVWR respectively.
And again, 25mph is the final ground speed, after the plane punted the truck and kept on going for 600ft.
>25mph is the final ground speed
Wouldn't final ground speed be zero?
Final ground speed reported.
Pause the video at 13 sec. That firetruck is awfully intact for something that allegedly got hit at high speed. Basically just a bunch of top side sheetmetal damage (concentrated to the rear, obviously). In any case it didn't even get sent hard enough to screw up the cab exterior. And on the flip side, if you keep cranking the speed up you start getting to where the plane starts looking too suspiciously intact. There's just not much room to work backwards from the apparent results and get a high difference in speed or get very high initial speeds (100 onto 75 or whatever). If the plane was going fast the truck had to be going fast too or there'd be more carnage. But if they were both going fast you'd expect more damage from the after the fact barrel roll and the plane and truck to be a little farther apart in distance.
Where’s the video you’re referring to?

I can’t tell what’s the truck and what’s the remains of the plane in this pic.
Another wider angle:

There’s no way this scene happens from a plane colliding with a truck at 24mph.
I'm talking about the headline video from TFA.
The back of a firetruck is not a working implement like a dump truck is nor is it sufficiently strong for mounting a crane or man bucket like utility bodies often are It's a bunch of sheetmetal boxes to hold stuff and cover stuff and there's a water tank back there somewhere. In the middle down low some pumps are buried. Basically don't think of it as being any more structural than a box truck body because it's not. All that stuff got shredded, obviously, since they're only really meant to bear their own weight and were subject to all the truck tossing forces here. Beyond that the truck is in pretty good shape. It's not uncommon for a good "off the highway and into the ditch" crash to rip tandems off, twist frames, etc. None of that has happened here. The plane is pretty rough, but that's expected. They are 100% tin cans. Ground equipment moving at idle speeds will absolutely shred them before the operator even feels resistance. A goose hit square on the leading edge of a small jet's wing will put a massive dent in (and apply red paint, lol).
24 sounds about right for a closing speed for plane onto truck. Whatever the baseline speed of the truck was cannot have been that high or the truck would be absolutely shredded from the barrel roll and as it stand the cab is barely pushed in.
The article dropped the speed claim.
The last recorded ground speed data of 24mph also shows a wildly different heading (going from 30deg ish to 170ish). So it probably happened after the collision and was part of its deceleration. As far as I know, the truck would have been crossing the runway so the effective speed perpendicular to the plane would be zero except for directional shear I guess.
> That's a huge amount of damage even at 24mph.
The speed was much higher per sibling comment, but also remember that kinetic energy also involves mass (planes are heavy) and the square of the velocity.
* https://en.wikipedia.org/wiki/Kinetic_energy
The latter is why (e.g.) going 100 units/hour has twice the KE of going 70 units/hour in a car.
It looks like that is based on the last recorded speed from flightradar24[1] which was 21kts(24mph). The previous data points were 11kts, and 58 kts(the last point before the track deviates off the runway). I do think it is likely that the collision occurred at a speed faster than 24mph.
edit: Looking into this a bit more it looks like the plane came to a stop around crossing E while the emergency vehicle was crossing at D(based on ATC recordings). Using the following map as reference[2], the 58kts point was around E, while the previous recorded point which was just before D was 114kts.

Very unlikely it was 24mph…The entire cockpit is gone.
(Though some of the major damage may have happened while deplaning the passengers)
On other hand planes are really not designed to be crashed into things. Only for limited impacts. So we might not have right comparison for relatively thin and aimed to be light structure being impacted by bulkier object.
Speed doesn't cause damage. Momentum causes damage. We understand speed, we do not understand momentum. It makes sense given our evolution.
People into boats need to understand this. Even a boat that travels no more than 4mph can crush you easily. This is why you never get on to moving boat from the front. Many people have made a mistake because speed is not high.
Tugboats bump other boats all day. Hundred thousand pound pieces of machinery bury themselves into the dirt. All this as part of normal operation. It's not that simple.
Speed, kinetic energy and acceleration are all interrelated and at the end of the day it's all forces (to some extent) and no amount of hand wringing commentary is going to replace genuine understanding of them.
How did it end up like that with the nose up: what is holding it up?
Gravity. The aircraft is heavier at the back, where the engines are. With the nose severely damaged/missing, the centre of gravity has shifted aft, so what’s left of the nose is sticking up in the air.
Front fell off, people deplaned (while still horizontal) which shifted the balance backwards. It’s sitting on the rear bulkhead,
I guess there is more weight in the relatively small section of the front that came off than I expected
I’d guess the front landing gear assembly is going to be fairly heavy, and appears to be missing. This model of plane also has its engines at the rear, not under the wing, which will move the balance to the back.
Oh yeah that definitely makes sense
Planes typically have their center of gravity just forward of the rear wheels. This makes it easier to rotate on takeoff.
The margins are thin enough that certain planes will sometimes have people in the back get off first, before the people on the front, to avoid tipping onto the tail like this.
Are the increased number of air incidents since Dec 2024 reflective of anything real or is it more attention on something? Brigida v. USDOT comes to mind but doesn't seem relevant. I'm sure we could all construct a chain of "this thing happened that caused that which caused this" and so on, but I'm curious if someone has done the effort to see whether such a chain is defensible.
Also, did the pilots die in the collision or in some sort of aftermath? The cockpit looks absolutely smashed.
You can probably construct a realistic chain of failure that goes all the way back to political tomfoolery and bad air traffic control leadership/staffing decisions, but that makes the wrong people look bad, so they'll probably blame individuals further down the totem pole like the controller or pilot and call it a day.
According to other news sources, the pilots lost their lives here, too.
The entire cockpit, front toilet and galley area, and probably a front row seat have all been utterly destroyed. Unfortunately I'd be amazed if the death toll stays at two.
It should be noted that aircraft and all other vehicle and personel movements on an airport are controlled from the airtraffic control tower by air traffic controllers or directly by individual flaggers, as directed from the tower. Or at least thats the way it is supposed to work, and of course the operation at a place like LaGuardia is more complex, and will have specialists and multiple zones. What will put an extra edge on this is the whole ICE thing, and airport chaos pulling the roof down.
> What will put an extra edge on this is the whole ICE thing, and airport chaos pulling the roof down.
How would the ICE thing cause more ground traffic collisions. Are you thinking ATC controllers are illegal immigrants and they’re going to run away during their shift? I just don’t see a connection there…
This incident caused delays and cancellations that ripple throughout an already understaffed network of TSA checkpoints. ICE presence will make airport security somehow an even worse experience for brown people.
Not the crash, but the aftermath. Passengers will be showing up for flights today, nervous with the crash on their minds, and many will then encounter untrained goons cosplaying as airport security.
I could see that, yeah.
The comments in /r/aviation see to think it’s a one (tired) man show at night.

Yet another blow to the confidence of flying in this country.
More accurately, the risk has increased by at least one order of magnitude, but the confidence of the public has largely stayed the same.
This comes to mind how during the Boeing news scandals, commenters would confidently argue "Flying is still ridiculously safe, statistically speaking", "these things happen every day, just underreported", and "you/people are irrational for not flying Boeing". It's a very curious argument to me. Is the ATC infrastructure issue analogous or not, etc.
Maybe US media, hardly an unbiased news source about US events, especially when hundreds of billions are flying around about incompetent massive employer and lobbyist.
Nowhere else in the world you would hear such statements. Boeings simply disappeared from Europe, those few that were here before. I am sure they are still used somewhere but I haven't flown any in past 7-8 years. Heck, I haven't seen any in South east Asia neither (but that may be due to luck).
I check this with all bookings, no way I am flying that piece of shit if I can anyhow avoid that, not alone and quadruple that with family.
It is strange. What is importa t is, are things getting better or getting worse? As they say, it’s not the fall that kills, bit the impact. Are we falling?
> "I visited them both in the hospital, as has the chairman, and they were able to speak and we're notifying their families," said Garcia.
Let's get the important parts out of the way first: We in charge have taken care of optics, with regard to our offices.
Oh, and we're going to contact families eventually.
I saw the first post about this on /r/flying and /r/aviation 5 hours ago and legacy media is only started reporting it in the last hour or so
/r/xyz doesnt need to fact check. Sure those are excellent subs but just being watering holes and not legal entities they can move faster. There were some wrong facts on r/aviation although it got viral so people just ploughed in with whatever news outlet they read it on.
I have seen a lot of first posts on social media which have been wrong
Nope.
CNN, CNBC, NYPost, Guardian all had stories up quickly, or around an hour. There are others too.
UPDATED:
Down-votes happen but disappointing since I'm stating facts. Heres some backup:
The user haunter said media started reporting around ~4 AM EST (based on timestamps).
The accident happened at 11:40 PM EST. Story publish times across a sample of various legacy/mainstream media orgs:
There are others.Is this a dig on legacy media? Do we expect people to be up all hours of the day reporting the news?
I got a NYT alert about this around 3:30am EDT.
Yes. Yes, we do. I expect a competent news agency to have a night desk.
Why though? To report to the people who are asleep?
And so much of the legacy media info is wrong. It’s strange because a lot of the primary sources are public.
This is a good overview so far:
https://m.youtube.com/watch?v=8vokLcNNGCM
Very informative, thanks for the link!
ATC audio is https://archive.liveatc.net/klga/KLGA-Twr-Mar-23-2026-0330Z....
The clearance for AC8646 to land on runway 4 is given in a sequence starting at 4:58. "Vehicle needs to cross the runway" at 6:43. Truck 1 and company asks for clearance to cross 4 at 6:53. Clearance is granted at 7:00. Then ATC asks both a Frontier and Truck 1 to stop, voice is hurried and it's confusing.
> And so much of the legacy media info is wrong. It’s strange because a lot of the primary sources are public.
You should provide sources for a claim like that. For example, what in the BBC article is wrong?
If only we could diff the BBC article (it currently says it was posted 21 mins ago which is younger than your comment…). It’s changed multiple times now without any kind of changelog or acknowledgement.
> Video footage on social media showed the aircraft, which is operated by Air Canada's regional partner Jazz aviation, coming to a rest with its nose upturned.
This just isn’t true. There’s no video of the plane coming to a rest with its nose upturned (which implies motion). The upturned nose happened only after passengers deplaned and the balance shifted.
> It had slowed to about 24mph when it collided with a vehicle from the Port Authority of New York and New Jersey, which runs the airport.
This is the next part that will change. Just because some of the last broadcast data said 24mph doesn’t mean that’s the speed it was when it collided with the truck. The truck is on its side and those passengers are in hospital. The pilots are dead. The plane sustained enough structural damage to have the entire nose collapse. If the sentence is based on that broadcast data, SAY THAT instead of printing it as fact.
And with all the quotes from social media posts from key groups, link to them instead of just vaguely quoting.
EDIT:
As expected, they got rid of the above paragraph claiming the speed. It now says:
“The plane was arriving from Montreal and had landed, before colliding with the vehicle from the Port Authority of New York and New Jersey, which runs the airport.”
Any of us can help log the changes by submitting revisions of the article to web.archive.org
With a fast-changing news story where vague/incomplete/conflicting details emerge in the first few hours it's not unreasonable for the first few revisions to be like that, and eventually gets fixed hours or a day later.
I think that’s what’s critical here. Post details and their sources to show that they are in flux. Don't write them as fact and then make secret edits.
Typically most primary sources are public.
It's hardly worth checking with the legacy media anymore. Really, why bother?
Why bother with the facts when you're already heard all the gossip?
At the very least it’s worth reading to see what most people / the people in power are reading or want others to read.
The NYT is biased, but it’s still basically the most official newspaper of the American ruling class.
Because some of them still have standards. They will correct themselves if something was wrong.
Everyone can write a comment on Reddit / make a podcast / video / whatever claiming whatever they want. Unless you already know and trust them (which requires you to be able to cross-check their information), it's potentially as useful as a random LLM hallucination. Could be brilliantly spot on, or could be completely nonsense. No way of knowing unless you already know enough. (Because even cross-checking won't necessarily save you, if you cross-check multiple bullshit sources).
Media with standards (like the BBC, Guardian, Liberation, etc.) will do their best to report truthfully (even if sometimes with some bias), and will fix their mistakes if they're caught later on or the story evolves. Independent media checking organisations have shown time and time again that there is trustworthy media, you just need to know which it is, and always take a pinch of salt. It's wild to me that people will just dismiss rags such as Fox News and relatively quality media like Guardian in the same breath.
