What I can't figure out is that the article states
"Langone said that once he was over the East River,
he received a radio call telling him he'd entered La Guardia airspace."

What I'm still trying to figure out is what "received a radio call"
means. Radio contact is generally initiated by the pilot. If he was
lost, what frequency was he on, and whatever it was, how did ATC know
what it was so they could call him?


I guess while he was at it, he should have flown south to D.C. and buzzed
the Washington monument.
