Thanks, but is it that straightforward to identify which is which ? The idea that a current did the sorting and filtering looks difficult if the fan casing positions are compared with teh engine locations: there is no consistency. Think there must have been more to the impact sequence than a belly flop. Also, an impact capable of chewing up the fuselage as shown by the debris is capable of breaking the structure into separate parts which then have their own impacts after a short travel of their own. Presumably something like that is necessary to explain how the galley structures etc 'escaped'. For example, it looks like the cockpit stayed in one piece until a rough impact with the sea bed.
