Let's stick to facts
Quite an interesting discussion on unusual attitudes...
But the point is, to get out - with any chance of success - from an unusual attitude, a pilot shouldn't be the prey of some major disorientation, disorientation that led him to the dire situation he found himself in, in the first place.
Manual flight, at night, total IMC, no natural horizon and thunderflashes, one 180 ° right turn after takeoff, followed by a left turn, and another one, while climbing, IMO that's enough recipe for somatographic illusion.
Then the succession of disorganised reactions to the body accelerations, the cockpit warnings - bank, stall, overspeed...- to the brutal ending of a death dive, probably an attempt to pull out at a very high G (in excess of 4 ) thus causing the in-flight break-up of the airplane (simultaneous losses of DFDR recording and ground radar trace of the flight).
When will we really address this somatographic illusion killer with some real training ? because, you know, the performance of modern airliners isn't really decreasing, flight controls will have quite a lot more authority than they do now... that problem isn't going away.
