OK - the answer is that we are in uncharted aerodynamic territory and thus don't know, and subjectivity rules. Even given that, I cannot understand Dani's "When the captain came to the cockpit, it was already impossible, aerodynamically and CRM-wise." since the a/c was above 35k - over 3 mins from impact..
The thing about 'cognative bias' is that it is very similar to instrument disorientation exercises - the teaching is to trust the instruments and IGNORE the 'bias'. Here, of course, the big unknown is what the instruments were telling.
