PARIS (AP) — The co-pilot of the doomed Germanwings flight repeatedly accelerated the plane as he used the automatic pilot to descend the A320 into the Alps, killing all 150 people on board, French investigators said Friday.

The BEA agency said in a statement that investigators have begun studying the black box data recorder from the plane, found at the crash site Thursday.

It says an initial reading of the recorder shows co-pilot Andreas Lubitz used the automatic pilot to put the plane into a descent and then repeatedly during the descent adjusted the automatic pilot to speed up the plane.

Based on recordings from the black box voice recorder, investigators say Lubitz locked the pilot out of the cockpit and intentionally crashed the plane, killing everyone on board.
