Forgive me if this has been discussed already, but in re-reading the Interim BEA report, I noticed that in the wreckage recovered on June 7th (page 102, lower map, also on page 108), there is a piece recovered very close to the last known position, while all the other debris appear to be further north. Do we know what piece this was or have any idea how it got separated from the rest. It would seem to me that either that piece broke off at a different point than the rest (perhaps an important clue of what happened while the plane was airborne?) or that it somehow managed to float in a different direction than all the other debris. Any thoughts?
