Going back to the EA762 Incident;
It was pretty successful given what was going on, though it could have gone better had the wings been level on landing, because when it hit the water, one of the wing-tips turned the a/c around.
Now that much Aircraft, doing a 360 at that speed, in such a short turning circle meant the ac broke up far more easily than it would have done, had just the engines touched the water and scooped up the water.
Although, like I said, I've not idea what was happening on the flight deck for the pilot to have turned the plane like that - one of the terrorists could have been up to no good, etc.
Though even more passengers than this could have survived, had it been made more clear to them that they shouldn't have inflated their life jackets until outside the a/c - it's vital the pax know just how important that is.
