the aircraft's nose may have fallen through,
HazelNuts, I did not mean the Nose would fall and everything was ducks, I meant that as one of only two airframe cues for STALL, it's lowering against the stick would have some warning value to the pilots, as intended in a normal aircraft.
Bear in mind even BEA had to ask experts if the accels in the DFDR traces were buffet, suggesting the pilots missed that one remaining cue, perhaps missing it in the turbulence.
In the approach to Stall recovery that is trained, the nose does not drop, so a non dropping nose and no buffet may have meant: " I knew it, that stupid Stall Warning was bs..."
