I find it interesting that New Yorkers are so adept at being able to identify helicopter noise out of all the traffic cacophony that permeates the state. It reminds me of the time, years ago when the Concorde was beginning flights between London and JFK airport in New York City. The city announced that it had set up a telephone “hot line” so people could call in and complain about the noise of the aircraft if they felt it was excessive. On the day the service was to start, the hot line began receiving calls several hours before the plane actually arrived at JFK.
