Hi, and eventually sorry by advance if this have allready been said.
It seems to me somewhat indredible the aircraft computers did not give any warning: as they were registred by the "black boxes", the vertical speed AND AoA were "known" by the computers. Even if there was some abnormalities about air speed , those datas had to trigger some warning: they, alone, were the sign the aircraft was stalled and falling.
About the NU inputs: somebody has told they can be the result of PF thinking of windshear. It would be very interesting to know about the two or three last simulator trainings of the PF (and other two crew). If one or more of those trainings were about windshear, maybe he (they) had (have) a tendancy to reproduce this case. It is a phenomenon well known, in medical domain for example: if you read some litterature about a rare pathology with relatively common symptoms, you have a tendancy to think about this one if your patient has those symptoms, even if it is not the most probable, statistically speaking.
