F-22 prototype crashes due to Pilot Induced Oscillations

What happens in this video ?

On April 25th 1992, this F-22 prototype crashes on the runway at the Edwards Air Force Base. The plane pitches forward and back 40 feet (12 m) above the runway, lands hardly without gear down, slides 8000 feet (2400 m), and partially burns. The pilot was not seriously hurt.
Investigations showed that the accident was caused by Pilot Induced Oscillations (PIO happens when the flight controls reacts too slowly in regards to the pilot orders).

I bet it was Microsoft Windows which caused the failure :) Anyway, we wouldn't be suffering from it if Windows was really the cause.

"PIO happens when the flight controls reacts too slowly in regards to the pilot orders" is wrong!! PIO is caused by pilot overcorrection, not slow flight controls. http://en.wikipedia.org/wiki/Pilot-induced_oscillation

This accident was actually caused by faulty soft ware in the flight computer not by pilot inputs.
