well... it truly sounds amazing that THREE people did not recognize a stalled situation for minutes. with a massive descend rate , simultanous high pitch and lack of airspeed it should be clear for every pilot what is happening. airbus is to blame that it did not firmly and continiously informed the pilots that they are in a stall.
so in the first moment we all could think we would made better, the aircraft from that high altitude surely was recoverable from a technical point ov view.
on the other hand it is always easy to discuss NOT being in an direct life danger. they were at night conditions, thunderthorms in the area, turbulence , no visual horizon reference, erratic airdata informations, and they panicked in a situation they never saw before.
all in all it nevertheless seems to be an massive pilots error- they could be able to keep out of the stall or recover one .
