Tourist`s post "For those that think a 777 could not land in one piece on the water ".
The Hudson glider experience proves it can be done, but and that`s a big BUT, subject to:
Strictly the A321 did not end up in 1 piece, the lower aft fuselage was pretty much torn off.
However, I am not sure the question is whether it can be in "1 piece" or not. It is whether it will remain intact enough to sink without much trace, or whether it will disintegrate to such an extent that light debris, even bodies, will remain floating to be found.
I have little doubt that a 777 could be ditched without the cabin (where the light stuff is) disintegrating, and thus sinking without trace. Whether that happened here ???
