This point may well have been made earlier & I have never operated any type of Airbus aircraft, so apologies here.
However as I understand, it is being fairly strongly sugested in some quarters, that in this incident there was a sudden & very excessive pitch up. Was this not exactly what happened a few months ago to the Airbus over North West Australia? Not making any point at all, but might this be food for thought?
Nice to see that the Crew Members who were recovered, have been released & will shortly return home for the last time. I do hope also, that at some stage in the near future, the final two Crew presently unaccounted for, will also be able to make the same journey. RIP
