this case isn't "Galloping Ghost". On blacking out, which follows grey out for positive g, the elevator input would have decreased only with some certainty at the point of losing consciousness, but the term blacking out does not itself indicate the loss of consciousness. On G-LOC, a loss of consciousness, and the aircraft would have reverted to a flight path as a consequence of the trimmed speed from the THS at the time that the aircraft was last in trim. What was the story that the jury heard?
For many G-LOC cases, if the aircraft is at a high bank angle, the speed stability (AOA stability) will result in increasing loads as the spiral tightens. In this case, the wings were level, and the aircraft would pitch to achieve the in trim speed one way or the other, without intervention by the pilot. However, the pitch angle at initial ground contact suggests that there was someone pulling strenuously on the controls at that time, and that means the pilot would most likely have been conscious at that moment. The exact condition would be determinable by measurement of the stabiliser actuator if it remained anywhere near intact.
If he had been professional accident would never happened. He wasn't. I get my coat.
