Sadly during our basic training we only do low speed stalls. Without moving into a delicate area I wonder if one of the 737 'rudder hard over' cases could have been saved if the crew were more aware of the high speed stall. It was some years ago in my previous company I attended a 'Jet Upset' course and I was suprised at how little I understood the high speed stall. Natural instinct when the window is full off ground is to pull back, but when you release the back pressure and unload the wing you can recover in some cases. I found it was a gap in my knowledge that was quite disturbing. One of the best courses I ever did. The ex-military people seem to have a better understanding and it's something the civilian trained pilots need to address. It's the angle and loading that hurts, not the speed.
