And how far might this debris if it is it, drifted from the original place of impact (see comment on the powerful winds that can hit that area). Would they ever be able to find the original spot?
Also, for that size of debris, considering the possibilities, I guess it could be part of an old ship. There aren’t many possibilities.
The large piece could be a wing or part of the fuselage.
Any one have a map showing the current flow for this area?
Lot of odds things in the sea. Things drift for years, especially after tsunamis. The Indian ocean was the site of a rather large one ten years ago.
