Just a small point:

+17.9 ANU was reached at 2h11min07, about 10 seconds after the airplane stalled. More seriously:
If the CM2 believed that aeroplane's behaviour and performance were the same at MSL and at FL330, then we are deeply and truly effed.
Perhaps 'believed' is not the right description, maybe his memorization of the UAS 'drill' did not go past the first line. Much has been written about the first seconds following A/P disconnect and the confusion and incomprehension that followed the stall, but in comparison very little about the stall itself. By 2h10min40 the PF had mastered the lateral control problem, his speed (F/O airdata on 3) still erroneous, the PNF had told him "watch your speed, you're climbing, go back down", in the next 10 seconds the PF had responded by reducing the pitch attitude to 6 degrees and the RoC to 1100 fpm. Why on earth did he start pulling again at that point?
