The Boeing 757's Flight Profile Duplication

Boeing 757 was able to demonstrate recovery of a similar flight profile with the application of maximum throttle and the application of proper flight commands for the recovery from stall. The crew did not take proper actions necessary to prevent loss of control of the aircraft on approximate replica of the flight in a training simulator provided investigators the opportunity to observe alternate actions. Investigators concluded the atmosphere of confusion continued between the three pilots while the aircraft lost flight control and descended to the sea. Boeing company informed the investigators that engineers during flight had inadvertently entered into a same flight profile during the development tests of the aircraft.
