I can tell you this: Situational awareness is not overdone, ever. Once the status is lost, (forget the instruments), the odds go long. Recovery from upset is taught, and tested, ab initio. As is STALL. When the important instruments go sour, and the airplane is not recovered, quickly, the rest is guesswork, random.
It boils down to "Sit on your hands" or "recover the bank angle and PITCH."
This flight was doomed well before the STALL. At least one pilot, the one flying, was done in rapidly, he lost his grip on the situation. The second one shortly thereafter. (Else why the frantic call to Captain?). The folks who continue to claim this was business as usual are holding an illusion. The a/c needed correction, at least in the mind of the PF. Can that be argued? To what point?
The Captain had to climb up the aisle at quite an angle. One g, in the pilot's seat, is quite different than having to ascend a ramped aisle.
He entered to STALLSTALL, and a confused crew. "Er, What are you doing?"
Shortly thereafter, he lost the plot. Check that, he never had it, and it was not forthcoming.
Bend over in the crosswalk, tie your shoelace, get flattened by a truck. Same-o.
