We developed a system in which we would point the aircraft straight up or some other direction and without pre briefing watch the recovery efforts of the pilots, it was an eye opener! Some tried to push over with the resuling negative G and all the interesting thing that this would produce, engine flame outs, hyd pumps cavitating ect.Once we taught the "one G' roll towards the horizon recovery, things improved to the point that all our pilots were flying out of these situations without any problems,
I've seen more than one civilian manual/handbook that has this one as the proper technique. I guess these are written by people who never did recoveries in real time (training).
If I ever need to use it in reality, I'll use the one I learned and thaught in the military.
