Obviously, and especially after reading your last, I am struggling mightily to get a handle on the initial events. You say it so well, and I am ironically satisfied that anyone would single out my struggle for flame.
At some point after origination of PITCH UP, (not the command, the actual), the a/c "began to climb". Does this indicate a gaining of altitude, or arrival at, or transition through, sufficient AoA to enable altitude increase? It enters into question the lack of STALL wrn, but, due Cavalry Charge and MASTER CAUTION, (A/P loss), was a STALLSTALL missed? Logically no, for BEA say the WARNING was "two" in number. implying a cessation of the original WARN at PF's first inputs?
(HN39. Is it at all possible that PF's Right and Left roll commands were in pursuit of an angle steep enough to cause the Nose to fall? It seems too early for such a "desperate step"?)
