You are right Takata. I think I'll have to ease up on Bear a bit. I fully agree with this view of his, at least in the latter stages of the fall to the surface. Earlier, I am not so sure.

not even bear thinks this airframe had greater than 90 degreees of AoA ('backward' flight)...
Have you a scenario that fits the endpoints? AF447 has been an enigma from the start. The only thing I know for certain is that Newton's laws were not repealed.

Tubby's concept is not only slightly over-elaborated, it just doesn't fit with many facts. My point about the possibility that engines would have experienced some notable troubles during such "4.5 minutes deep stall" is only one amongst many others in opposition to such conclusion.
Well lets get started. Let's examine these facts.
My favorable experience with jet engines at high AOA does not include experience with Fan type wing mounted engines. Why are Fan type engines so much more finicky (if they indeed are)? And as always, others are welcome to join in.
