The New York Fire Department said there is currently one fatality reported. It does not appear anyone else was on board when the crash occurred at around 2 p.m.

In a briefing with reporters, New York Gov. Andrew Cuomo told reporters that the aircraft had to do an “emergency, crash” landing. The governor added that there was “no indication it was more than that,” adding it was still early in the investigation.
