Technically, you are correct. However, due to noise ordinances in New York City and Queens County where the airport is, LGA
does close at midnight.
Sounds like everything is pretty much okay, though. This kind of incident occurs all over the US all the time (perhaps once or twice a month, maybe more). It's the first evac of a 717 that I've heard of.
Also, the article makes the statement:
But the pilot managed to land the plane safely at La Guardia then opened the plane's emergency chutes.
Isn't it the responsibility of the FAs to open the chutes? Or can it be centrally controlled on the 717?
Those who fail to learn history are doomed to repeat it in summer school.
