ap08,
The Airbus that stalled at high altitude, had trimmed itself into an AOA 40 degrees, with zero chance of recovery and survival.
The scenario you describe has been thoroughly discussed by some very well-informed posters, (ie, pilots, aeronauticists etc). I think you need to do some reading from previous posters before concluding that there was "zero chance of recovery".
Theoretical recovery possibilities have been studied and are presented
here. Sim work is discussed at length throughout threads 6, 7, 8 & 9 - one recent example is
my own. Though not driven by actual data, the approximation of aircraft behaviour at and beyond the stall is sufficient to explore recovery possibilities more thoroughly. However,
post #457 on Thread #6 from
Owain Glyndwr is well worth reading on the topic of the effects of the THS, the subject under discussion.
