I believe it was responding to the other active incident that the ATC was also handling where a plane failed to take off?

Was the 2nd plane on a runway still also?

it was on a taxiway. The fire truck had to cross the runway to get to it.

>> One controller overnight is completely reasonable So if said controller has a medical episode?

"Funny" enough if this controller had had a medical emergency (or just bad sushi) and been off the radios, this wouldn't have happened because the fire truck would not have received clearance to cross the runway and wouldn't have. Or at least would have crossed like the airport was uncontrolled, been much more careful and announced itself, and likely have seen the landing aircraft.

And if an aircraft needs to land due to an emergency? It’s amazing things work as well as they do, the system relies on only one thing going wrong at a time. This accident was an example of multiple things going wrong at the same time.

How do you know it was due to staffing shortages? It is common at LGA for one controller to be handling Tower and Ground late at night.

You are describing a staffing shortage.

Is he? I can see the number of hours worked as evidence of a shortage, but prima facie it is not obvious that a single controller handling both ground and air is evidence of a 'shortage' if it is routinely considered feasible in the industry. It could just be an efficiency choice for low-traffic times. Based on some googling since I'm not an expert it seems this is called 'position combining' in the US and is pretty routine across the world. Therefore, if this is a problem the primary cause cannot be US policy because non-US airports also do this thing.

Here it's being done at SFO or so it seems: https://data.ntsb.gov/Docket/Document/docBLOB?FileExtension=...

While searching I did find this other document where a GC (LC appears to be Local Control for local air traffic and GC is ground control) controller complains about combining due to short-staffing https://data.ntsb.gov/Docket/Document/docBLOB?ID=19837915&Fi...

Well, it'll be an interesting report from the NTSB at least.

> I still haven't seen evidence that they were running understaffed at that moment. I think the disagreement you see is based on the definition of what "understaffed" means. Having one ATC to do ground and air control simultaneously seems like an under-staffing situation to begin with, regardless of whether it's a common practice.

There is also the angle of: even if there is an appropriate amount of controllers in the tower at a given time, how they do it can also hint at the issue. Being an ATC is a taxing job, mandatory overtime and 60 hours work weeks screams understaffing to me.

It is possible for ATC to be understaffed as a profession, LGA to be understaffed as an airport, individual controllers to be overworked, and for it to be 100% reasonable to have a single controller at LGA in the middle of the night.

I can’t find a way to read this other than “If we remove regulation and safety controls, things will be safer because everyone will be more careful.”

I just hope they don't try to pin this on the controller who was on duty and move on without putting plans in place for some sort of structural change. Controllers are forced to work 60+ hour weeks and overnight shifts, and the controller in question was working both ground and air control simultaneously due to staffing shortages. If you listen to the ATC audio, he was handling finding a spot for a plane that aborted…

> the controller in question was working both ground and air control simultaneously due to staffing shortages How many planes land at LGA in the middle the night? One controller overnight is completely reasonable.

Normally? Zero. LGA has a curfew from midnight to six AM, April 5-December 31.

In practice? It depends. Delays have a tendency to cascade in the air travel system and the Port Authority can curtail or cancel the curfew at their discretion. How frequently do exceptions to normal ops have to happen for it to be unreasonable to use "normal ops traffic" as a justification for scheduling a single controller? Ultimately, controllers have to control the traffic that they get, not the traffic that they want/expect to get, and a system that is overly optimized becomes brittle and unable to deal with exceptions to the norm.

It is surprising to me that airports do not use an interlock system for deconflicting the various paths segments that may be occupied by a vehicle. Trains have used mechanical ones since the 1800s [0]. The story and comments seem to indicate the only thing preventing collisions is the mind of one person--that sounds insane. 0. https://en.wikipedia.org/wiki/Interlocking

If school busses can look both ways before crossing train tracks you'd think a firetruck would look both ways for airplanes coming down a runway. Don't want to blame the firemen though - this was a series of extrmeemly unfortuante scenarios and people trying to keep the airport running safely. For years people have been on soap boxes saying the FAA/NTSB needs to do better, and yet year after year they are poorly run and poorly funded.

And therein lies the problem. Clearly, having one overworked controller running a combined tower is not safe nor sustainable.

Planes landing at a rate of one every 30-40 minutes isn't exactly "overworked."

12am-5am is very quiet, at about 1 per hour. But the accident happened during the 10pm-12am time slot, which is not as busy as other times of day, but can still have workload spikes as evidenced by this situation.

ATC should never work alone at any of the "Core 30" airports. https://www.aspm.faa.gov/aspmhelp/index/Core_30.html

You should try harder, because I'm not making any comment on regulation whatsoever. There are procedures that every controller and pilot knows for how to handle loss of radio contact.
