Until it is shown that the pilots knew they were in a stall. Mr.O

Bear, is that "mush" not a stall? ...
Of course, an unannounced one. What does she do at 60 knots and 48 AoA?

How do the pilots know? BEA report one STALLSTALL, then PF NU, and no STALLSTALL? They were not properly introduced I'm saying. By now, without a NOSE DROP, THS has no authority, it is Stalled further if ND is input, and if effective, the Nose goes UP, NOT DOWN.

Was the stubborn NU on the way down an attempt to get her to BREAK?

Or was he getting most of his "Nose Down" from pulling back? IOW, full back dropped the nose (it would), and pushing caused the Nose to rise. (also true). The Horizontal Stabilizer in this extreme aspect would behave like a spoileron, or spoilerator, getting authority from drag only, not aero.


wadda ya think
