My confession is that I believe PF was not utilizing a version of "pull back hard it will not Stall..." I think he was honestly trying to regain a cruise Pitch or thereabouts. I do not think he was instantly on board with UAS, and all that it demanded. Whether he sussed it ever is arguable. The data is insufficient to make a perfect conclusion.
So I agree with Infrequentflyer. This accident is not well understood, but it does not suggest that anything like it will occur at all, ever.
bubbers, by " not well understood " I mean by me.
