Early speculation on reasons for the crash of Air France Flight 447 blamed an unrecoverable deep stall since it descended in an almost flat attitude ( 15 degrees ) at an angle of attack of 35 degrees or more . However it was held in a stalled glide by the pilots who held the nose up amid all the confusion of what was actually happening to the aircraft
