VASAviation has just covered a recent close call at New York LaGuardia Airport (LGA), which is just another example of the extent to which our air traffic control system needs reform.
In this post:
American jet takes off as United jet taxies on runway
This incident happened at around 12:30AM on Tuesday, May 6, 2025, at LaGuardia Airport. It involves two aircraft:
- United flight UA2657, operated by a mainline Boeing 737-800, had just completed a flight from Houston (IAH), and was taxiing to the gate
- American Eagle flight AA4736, operated by a Republic Airways Embraer E175 (callsign “Brickyard”), was scheduled to depart to Buffalo (BUF), roughly three hours behind schedule, and was taxiing to the runway for departure
LaGuardia is an incredibly congested airport with limited space for movement, which makes the job of air traffic controllers complicated. Here’s the play-by-play of what’s relevant to this incident:
- The LaGuardia tower controller initially advises the United jet to hold short of runway 13, as it would be using that runway to taxi to its gate
- A short while later, the LaGuardia tower controller advises the United jet to taxi down runway 13, exit at a certain taxiway, and contact LaGuardia ground
- Shortly thereafter, the tower controller advises the American Eagle jet to line up and wait on runway 13, in preparation for takeoff
- The United jet passes the taxiway it’s supposed to exit on, so the ground controller gives him a different taxiway to exit on
- While the United jet is still on the runway, the tower controller gives the American Eagle jet takeoff clearance, and it starts its takeoff roll (meanwhile a Spirit pilot is stepping on the transmission)
- At this point the tower controllers gets an automated alert about the potential collision, and tells the American Eagle jet to cancel its takeoff clearance, but at the same time, the Spirit pilot is still stepping on the controller’s transmission
- The LaGuardia tower controller says “sorry about that, I thought United had cleared well before that”
- The American Eagle jet ends up returning to the gate, and the flight gets canceled
Based on flight tracking data, it appears the plane reached a maximum speed of over 100 knots, prior to rejecting its takeoff.
This incident was so avoidable, no?
I think incidents like this are a perfect representation of how complacent we’ve become with our air traffic control system, even if it makes no sense.
The most obvious issue here is that a tower controller and ground controller are both controlling movements on an active runway, on separate frequencies. If you step back and think about it, that just makes zero sense. In a vast majority of countries, a tower controller wouldn’t hand a pilot over to a ground controller until they’re off the active runway… for obvious reasons.
Also, when the tower controller says “I thought United had cleared well before that.” Like, based on what? Did he check/look at the radar, or he just assumed because he assumed?
Then there’s of course the communication challenge of people stepping on the controller’s transmissions, making it difficult for him to communicate that there’s an emergency that requires immediate action.
Look, air traffic controllers are really hard working, and do an amazing job keeping our skies safe. The problem is that they’re working within a really flawed system. At an airport like LaGuardia, the runway and taxiway congestion level is just next level, and they have a challenging task.
When you combine that with some of the stupid concepts that we just accept as normal (like two separate controllers on separate frequencies having control over the active runway), of course incidents like this are going to happen.
Bottom line
We recently saw yet another close call at LaGuardia Airport, as an American Eagle jet was cleared for takeoff while a United jet was still on the runway. The pilots were simply following instructions, and the issue is that one plane was on the tower frequency, and the other on the ground frequency.
What do you make of this LaGuardia incident?
Had to reply to someone below, so pardon the tardiness.
This smacks of complacency, in three parts: the tower controller who assumed UA was exiting as directed, the UA crew who (generally and rightfully so) assumes the runway is theirs for as long as they are on it, and the RPA crew who were late, just wanted to get underway and accepted a takeoff clearance without full situational awareness (SA).
Lucky's headline of "This incident...

Lucky's headline of "This incident was so avoidable, no?" will apply to SO MANY future near-misses, and probably a few tragic losses. We have a huge number of pilots being pushed hard by their employers to fly schedules that continue to toe up-to-the-line of "legal". Most of these younger, up-and-coming pilots have a fraction of the experience of others in their shoes just 10-20 years ago. They don't know how to refuse a trip, their eyes are focused on getting to the next step at a major airline to get that moneyshot.
Our ATC system is overworked, understaffed, under-supported with old, botchy tech... and while yes, that should/could have been corrected in years/decades past, it is NOT unlikely the current administration is insincere about making any true improvements, but only about making positive headlines and holding their breath that the public will forget about it and let the whole circus carry on.
The Eagle pilots could not see United on the runway in front of them? I am sure brake cooling requirements canceled the Eagle flight.
Am not surprised at Spirit randomly getting in the way (of the ATC conversations)
Reduce the volume of traffic!!! Yes I said that. People can plan for time/routing that works but keeping pressure on ATC and the $$ profit is just plain stupid.
I think this is a big part of the issue. We have more air traffic controllers than ever before, but they're still understaffed and overworked because air traffic has grown much faster than the ATC workforce. Typical scheduling at the major airports depends on perfect weather, with anything more than short weather delays causing major cascading issues along the rest of the airlines' networks. You just can't expect a system to run at 100% capacity...

You just can't expect a system to run at 100% capacity forever with no issues, reality doesn't work that way, but that's what the airlines are trying to do.
As I understand it, the UAL plane had already landed and was on a taxiway, but needed to get back on a runway in order to reach the taxiway that would take it to its gate. Is that correct?
And when you write, "Also, when the tower controller says “I thought United had cleared well before that.” Like, based on what? Did he check/look at the radar," -- is there ground radar at LGA,...

And when you write, "Also, when the tower controller says “I thought United had cleared well before that.” Like, based on what? Did he check/look at the radar," -- is there ground radar at LGA, tracking movement on taxiways and runways? My understanding is that at many airports, the reason there are towers is because they are the only way to follow movement on the ground. You don't really need towers to see airplanes in the sky, do you? At least, TRACONs don't use them.
Starting to make it seem like the DEI policy was the only thing keeping people safe...
Damn. I just switched an upcoming flight from EWR to LGA precisely to avoid this kind if thing. I guess there's no escaping it.
Hundred of flights take off and land from LGA every day with no incident. You and everyone else escape disaster every day by design.
Could we also mention the United pilot did not listen to the instruction to exit at this designated taxiway? So it was double failure - mistake by the pilot and Air Traffic controller.
And the one common thing, both are humans.
Are we ready for Waymo? Works great on the ground for cars here in SF. You try first in an airplane though, virtually everyone on this board is more expert (and braver) than me. Waymo would not have missed the exit but might have freaked out (when Waymo freaks out it stops) about on oncoming aircraft.
It seems as though there are airports that have too many flights albeit this was at 12:30AM. Not exactly prime time for take offs at LGA.
you have got to get these transmissions sent via text simultaneously.
Having another pilot stepping on important transmissions is unacceptable.
Time for someone to make a decision and reduce capacity, I doubt the airlines or the airport wants to make that choice so the government will need to step in! It’s getting ridiculous and in the long term will harm public trust in the system the longer all these issues continue.
Can we please stop with these platitudes which are not even true? Certainly not in New York, the capital of mergers and acquisitions and other economic activities that require actual hard work. I've never heard of a single Air Traffic Controller spending 40 hours straight in the tower but that's exactly what corporate associates at investment banks and law firms do all the time when a deal...

Bankers and lawyers have an extra set of clothes and a stick of deodorant at their desk because the unscheduled all-nighter is so routine. These firms have runners to take dry cleaning to and from the office. Onsite doctors are available and--of interest to this travel community--CBP has held Global Entry interviews in the office.
Hard work means going to the office at 9am and still being there at 9am the next morning all while maintaining a sharp appearance and pleasant demeanor appropriate for client service interactions. I realize there is a stereotype of high financiers being insufferable twats and there are certainly such individuals (which I state with regret) but by and large this group is refined and high class on top of being the hardest workers you'll see.
It is an insult to say ATC are hard working especially in New York City where you find such a critical mass of financiers and lawyers. Lawyers at my firm routinely bill 3,000 hours a year when the average American merely works 2,000 hours and believes they deserve a medal for their hard work.
Let's calibrate our expectations of what hard work really means.
And now we've heard from the finance bro. Yes, we definitely want air traffic controllers working for 40 hours straight. That'll keep things safe.
Air traffic control is a *real* job, not like the leeches in M&A.
I take it you flamed out on the LSAT and couldn't get into law school because logic is clearly not your strong suit. I did not say ATC should work 40 hours straight (although I also did not oppose that idea). What I opposed was the notion ATC is hard working.
M&A associates are not leeches, they are what make the US economy the global powerhouse it is. There's a reason M&A is so lucrative...

M&A associates are not leeches, they are what make the US economy the global powerhouse it is. There's a reason M&A is so lucrative and "real" jobs are not. "Real" jobs add little value to GDP; the label "real" is given out as cope so poor slobs who, I suppose like you, lack the intellectual prowess to attend law school, can feel like something other than complete and total losers in life.
Oh, geez, finance-bro, speaking of logic fails, you're simultaneously chickening out of your first statement (whiny finance-bro voice: "That's NOT what I said! (sobs)") but then flipping around and saying it again. Good job. Would you like to settle on a position at any point?
And I dearly love the whimpering about "global powerhouse" and trying to measure everything by money. That's exactly what leeches would say.
I know he's back but I'd rather Tim than Arps
Agreed
Just stop with this. That lawyers and financiers work long hours (for amazing pay) is well known and also bad outside of exceptional circumstances. There are regular stories of finance people dropping dead due to exhaustion. That shouldn't just be part of the job. But if you get something wrong on the merger of Corp A Inc and Corp B Inc, no one dies. If you get something wrong on a runway, 300 people are...

Justify ATCs working even harder and making more mistakes?
Let's allow critical workers to get a good night's sleep between shits.
Also, lets let them get a good night's sleep between shifts. LOL.
I hardly think how much time someone spends at work is reflective of how hard they work.
This post is satire, right? If the expectations of hard work are NYC financiers, apparently I need to be drinking a lot more at work.
Dear lord ARPS, why don't you read the room already?!? When other readers are straight out wistful for the days when a xenophobic, racist POS would frequently comment, you've lost the room already. On one hand, I guess we should be glad you have the job you do, are as good at it as you say you are, otherwise it would be sad to think of just one more lonely guy in his parents' basement...

On the other hand, for such a successful guy are we to assume that you never leave the office or take holiday? When yo do, do you criticize all the service staff at hotels, or on the plane, or in the lounges and bars that you go to and tell them they don't know what "real hard work" is? The fact that you're such a one-note wonder only makes me think that you're a two-pump chump.
Have a little grace and try to keep your mind open to the fact that there are ALL SORTS of jobs out there that require all sorts of talents. And some talents, when fully realized, can be exhausting after just 30-40hrs of work a week. Or in the case of ATC'ers, 30-60mins at a time, 6-8 times, spread across 12-14 hours a day.
Amateur JoeSaurus wants a raise so human ATC can live like kings.
Time to keep the skies safe from human error.
It’s crazy to me that aircraft using/crossing a runway to taxi are on ground frequency. At my airport, any aircraft crossing or taxiing on a runway does so under tower’s control, not ground.
New York is such a shithole.
DJT, my friend, may I kindly take a moment to present another point of view? New York is a city where both extremes (extremely good and extremely bad) coexist to a degree not found anywhere else in the world.

DJT, my friend, may I kindly take a moment to present another point of view? New York is a city where both extremes (extremely good and extremely bad) coexist to a degree not found anywhere else in the world. This much is true of any entity in New York whether it is a person, a building, a restaurant, or an arts show. Within the span of 10 seconds in the city you can meet a horrible human being, and immediately thereafter, the most charming and personable spirit you can imagine.
Should one focus on the negative extreme, then New York is a shithole. Should one take the opposite approach, though, New York truly is the greatest city on earth. Steadfast adherence to a stoic philosophy and magnetism to the good extreme are needed to hold the latter belief.
PoliteNew …. Place in America!
I have marked your post as helpful because I totally agree with most of what you say. However, one does take exception to one sentence …. that guff about that New city on the Hudson. Please be advised that the real York has the claim to being the greatest York on earth …. :-)
