There have been one or two comments about the containers and the condition of the galley being in good order.
I'm sure that many of you know how relatively feeble is the retaining mechanism for the galley containers, how often they come adrift even after a gentle landing. Imagine then, an aircraft breaking up in flight, various parts spinning and spiralling into the sea, almost inevitably with considerable force; would those containers really still be there, in their stowed position? It would also be interesting to know how much water they contained as it might be indicative of how deep they went before surfacing, and whether the buoyancy of the structure to which they were secured was sufficient to bring them to the surface if they were water logged.
To me it is more suggestive of an aircraft breaking up on contact with the sea.
