Why ? Why did he climb ? His first action should be level off. PNF doesn't know either - his comments seem to imply PF is not aware he is climbing.

And what could go wrong if you climb inexorably - Airbus is the first a/c without a service ceiling ?

He's in ALTERNATE LAW, what could go wrong, he is Alpha protected?
He doesn't know his a/c flight modes / laws then.

Wicked speed, insane descent, He'll wait for the a/c to "raise" the nose.
Nose is already up - so you suggest he isn't looking at pitch either ?

What else could be wrong, it can't be STALLED.
Yep, because otherwise we'd have had a stall warning... oh, we did, for 50odd secs, but that's ok that's gone now because we've recovered from that stall, without ever putting the nose down...

He had it figured, wrong, but figured. His idea of recovery was to allow the a/c to recover, as it always does.
But it doesn't - or at least not as I understand it - in particular if you get into alpha-prot mode, you have to act to get out of it. Leave it there and I think you'll end up in a phugoid around your max alt.

Ultimately, all three figured to PULL was the call. ALL THREE.

It happened another way? Funny thing, Airbus pilots aren't quite as harsh on these three, wonder why? They know something we don't?
Maybe they also had no training (at all says the report), and no practice, in hand-flying at altitude. Maybe they have since had 447 scenario thrown at them in sim, before such training, and it didn't go so well... (or they have had the training and then the excercise and are thinking how they might have done untrained).
