The only things I feel I believe for sure out of all this are that not latching the stall warning is a clear design oversight and that trimming to near the maximum authority deserves a big red light all for itself (irrespect of 'use manual trim') -that was also a factor at Amsterdam wasn't it ?

However, even if they had recognised the condition and then acted appropriately, recovery from 20000ft would have needed at least a continual sustained 2.3g positive acceleration, and from 10000ft 3.6g. A non-optimal response would have needed more by a factor. With the instruments they had with degraded protections, was subsequent recovery even likely ?

Edit: thanks HN39, merely a factor of 60 out so pls ignore the g's.
