Speculation
The water landing was a fantastically skilled piece of mitigation, of that there can be no doubt. But...
...Why is it that when the flight crew are criticised, everyone says " Wait for the report", and yet when they are praised as heroes, posters accept immediately that this is the case, with flowery speculation about what might have been happening on the flight deck...
We do not yet know what happened, other than the fact that the situation was well mitigated.
Wait for the report.
