Just watch this video clip and see for yourselves just how nasty the F-22 is in a stall!
go down the page to F-22 stall test video.
Unfortunately, N22YX was involved in a major accident on May 25, 1992 when it belly-flopped onto the runway after 8 seconds of violent pilot-induced oscillations. It slid several thousand feet down the runway and caught fire, destroying some 25 percent of the airframe. Pilot Tom Morgenfeld was uninjured, but the aircraft was deemed too badly damaged for economical repair.
At the time of the crash, Morgenfeld had been carrying out a planned go-around, and he had just switched on his afterburners and had retracted his undercarriage at less than 50 feet off the runway with thrust vectoring active. At a speed of 175 knots, the aircraft began an uncommanded pitchup followed by a severe stick-forward command from the pilot. The aircraft then entered a series of pitch oscillations, with rapid tail and thrust nozzle fluctuations, exacerbated by control surface actuators hitting rate limiters causing commands to get out of synchronization with their execution.
An investigation later showed that Morgenfeld had ignored a test-card that required that the vectoring nozzles to be locked into position in just such a configuration that he had found himself at the time of the crash. However, most engineers had also ignored this instruction since they thought it to be unnecessary. At the time of the accident, the aircraft had made some 760 flights and had logged 100.4 hours in the air.
