'Flying upside down' is certainly valuable (I offer spin training to all my students who want it, since it does not require a parachute) but it would not be very helpful in the case of weather related disorientation. JFK accident was more of a failure in decision-making than the piloting skills. 'Do not fly angry or upset' is a basic rule. It is incredible what people decide to do after gaining just a modicum of confidence. Even those who claim they are obsessed with safety. I had an airplane owner and a student who once tried to convince me to fly a twin after one of the engines shut down on take off (fortunately we were still slow)! His family was on board! He was not my student for much longer.
