Adam Air Flight 574
By the time the captain realizes what is actually happening, the aircraft is descending at negative 60 degrees nose down and 110 degrees of right bank. Captain Widodo takes control of the aircraft and attempts to roll the plane wings level, but is spatially disoriented by the lack of visual cues outside of the aircraft and completely ignores his attitude indicator. "Pull up, pull up!" First Officer Susanto screamed. Then, at a speed of Mach 0.926, Widodo pulls back on his yoke, contrary to existing upset recovery procedures. The horizontal stabilizers then separate from the aircraft, leaving it completely uncontrollable. The aircraft's G load then rapidly reverses from 3.5 G to negative 2.8 G, then continues to pick up speed until it crashes into the Makassar Strait.
