The only addition to the STALL discussion is that these guys were NOT treated to the standard airframe cues of STALL. Did they hear the actual STALL WARN? Did they feel vibration, loss of noise of airstream, etc?
Later, out of energy and PITCHED up, there was no NOSE drop, and prior, there had been no BUFFET, a clue to imminent loss of lift.
What were the feel cues? What about this STALL entry was so unlike what might have reasonably been expected in Vanilla Stall? Further, what about this entry hypnotized all three into functionally eliminating STALL from the list of possible failures?
It is not complicated. Yet it continues to be passionately discussed. In the Flight environment of the instant, one only has instruments with which to troubleshoot. Before making judgments, it would be best to more fully understand the instruments, and those that failed.
And try not to be seduced into a post mortem of the part of the flight that is selling newspapers, and is virtually bankrupt of lessons, and ultimate justice.
