She impacted with a velocity around 240 knots.
"sixty knots" is extraneous information. A pilot who confuses a reoccurring Stall Warn and increasing velocity with decreasing Pitch such that he pulls back, is too in the weeds to fly. Neither of the other two could have done any better, using available data from CVR.

From the BEA final report:
"Les dernières valeurs enregistrées sont une vitesse verticale de - 10 912 ft/min, une vitesse sol de 107 kt, une assiette de 16,2 degrés à cabrer, un roulis de 5,3 degrés à gauche"
So I understand that VS and GS were the same 107 KTS at impact.
I am wondering why would a Ground Speed be only displayed on the ND, and not on PFD? Isn't it a strange design?
A glance at GS and you can guess if a stall condition might exist, at any altitude. To have to look at the ND is not optimum in such a scenario.
