Local reports of eyewitnesses say an engine came off first, and landed separately from the plane. The plane came in "flat," not nosediving, thus perhaps somewhat under the pilot's control. Plane was zigzagging before it crashed. The A300 can be landed without power, thus stable with both engines gone. The engine that came off could have caused destablization. No evidence of an attack. However, terrorist games often include scenarios of an ground to air attack on planes leaving Kennedy as they pass over the lightly populated areas of Queens (a lot of open water and marshlands). No eyewitness accounts of missile tracks. One witness of the engine falling said he heard no explosion beforehand. Another said the sound of the plane was unusual, more like a jet fighter than an airliner. Jet fighters are on regular patrol around the city and NY airports. As reported, bridges and tunnels closed, except some outbound traffic allowed. Phones here are jammed.
