Preliminary reports indicate part of the Boeing 777 might have washed ashore on Reunion island. Here is the latest CNN report. And here is a useful summary from Aviation Herald. To this untrained eye, the photos show remarkably little sea life attached to the debris. However, what plants and crustaceans are found there will help determine the history of the object after it hit the water.
Preliminary statements indicate that Reunion is a reasonable place to expect debris from the calculated crash site to drift to. In Bayesian terms, this means the new information gives us no reason to change our original conclusion.
