I’m not an airline pilot but a medic. In the end result, this is a similar crash to AF447 in that there was a very distracted crew in an aeroplane that had its automatic protections off, who were then unable to recognise a pilot induced stall and kept the plane in a stalled condition until it crashed. I can’t believe that experienced pilots don’t know about stalling. There will be other human factors involved such as psychological barriers in a crisis to accepting that the familiar rules have just changed, and that a normally “unstallable” aeroplane might, on this occasion, be doing just that. This should be considered as a training issue.
