The Atlantic Ocean is an incredibly hostile place. If the plane broke up in flight doing 400 mph at altitude there wouldn't be many large pieces left, of anything.

Just another fragile ecosystem mystery;
lost within the ozone hole of history;
while oceans boil and species spoil;
we dash about and thrash and shout;
the air grows thick the seas go slick;
and all above becomes below;
and so it goes;
and so it goes.
