Possible first evidence of a wing and luggage being washed up on Reunion Island
http://www.bbc.co.uk/news/world-asia-33714780Bearing in mind there are no other 777's unaccounted for, this should be easy to verify. You would expect that more debris would start to wash up in the coming weeks and months.

The items have washed up 6000km from where they were/are looking for the plane wreck.
Guessing the main debris field will be miles underwater which will make it almost impossible to find.
