It's puzzling to find such a large internal structure (portion of galley), without finding any smaller pieces of the same obviously buoyant material that it was attached to. Like finding a bedroom closet in the middle of the woods, with no bedroom in sight.
Of all the items on an aircraft, the galley is nearly the last item I'd expect to still be floating after 16 days. Since it was, I am surprised there isn't more of this plane to be found within eyesight of this piece (subject to the exact same currents)?
More data brings exponentially more questions.
