AF 447 crashed because the pilots allowed it to stall.
Correct
The pilots allowed it to stall because they pulled back on the stick.
No. Because they made totally incorrect control demands.
They pulled back on the stick because they were confused.
No. Because they were completely incompetent and had received utterly inadequate training.
They were confused because the automation left them in the lurch.
No, it didn't. The AFS acted correctly and disconnected with a clear annunciation. The idiots at the helm didn't follow the QRH, let alone commonsense.
The automation left them in the lurch because of a mechanical problem with the speeder tuber thingies.
By 'speeder tube thingies', I presume you mean pitot tubes. They failed, it is true. However, all that did was to cause an entirely recoverable situation for properly trained pilots.
The rest of your post is utter tripe. An ill-disciplined, poorly trained crew killed themselves and everyone on board through their own inadequacy.
