Software glitch:
Megan,
As I understand it, all that you wrote is true. You didn't mention that the Push-To-Reset function was incorrectly connected to an incremental increase in the helicopter flight mode collective position of one of the rotors, The rabbit punching of the reset button incrementally increased one of the rotor's collective position (which was obviously not understood by the pilot) until the aircraft rolled over and went in. This is the software glitch I was referring to. (Correct me if I'm wrong.) Ott.
