Investigators are still trying to determine why the personal aircraft crashed into a luxury high-rise in New York last Wednesday. Last week, officials successfully recovered many parts of the aircraft including the nose, wings, tail, instrument panel and a GPS device. At this point, it appears the plane was flying at 112 mph when it tried to make a u-turn to follow the East River; soon after the plane fell off radar. Preliminary investigations indicate the engine was still running when the aircraft crashed.
