n77, nice one!
I am not sure a master's degree would be of much help in that very moment, more so the practice and the experience learned from people with more grey hair...I have done the inverted spin once in an aerobatics glider (ASH25 if I recall), with the help of the instructor...still trying to figure out how it all happened...
Anyway the NTPS course is very much about theory, lasts about a year, brings inside understanding. Testing is not about spinning in all directions, unless you be a test pilot for aerobatics.
I doubt any airliner would be doing inverted spins as part of their certification programmes..
Sorry, off topic...
