Jet Jockey A4:
The autopilot wasn't off for 90 minutes, it disengaged aprox 4 minutes before the crash because of (suspected) pitot tubes freezing up, and resultant confliction of airspeed indications (causing the systems to revert to 'alternate law', or in English, over to the pilots). They weren't hand flying for fun!
You seem to be slightly unfamiliar with this case.
I agree with you on the training front, and when I flew I also had extensive training in stall recovery and UA recovery with a variety of parameters. So your comment 'I just don't get it' has total agreement from me, mate!
