The AAIB report shall stand on its own, and I would accept its findings with confidence. My "so true" is my expression of concurrence with the statement I quoted. I agree with the notion that the pilot accepted responsibility of control of the aircraft, and, while exercising that control the aircraft ended up in a very bad place.
Had the pilot made different control inputs, the plane would have ended up somewhere else. I think it is very true that pilots must always understand where an aircraft could end up based upon their control inputs, and fly accordingly.
I have always flown considering that conclusion, no jumping required....
