We all want the answer, but...
can any of the experts here imagine a scenario where a B777 crashes into the jungle and there are still identifiable body parts inside, never mind a skeleton with headset still attached?
Meanwhile, we have the Inmarsat data that puts the aircraft somewhere in the Southern Ocean, and we have a flaperon that has been shown through forensic examination (that is, sufficient say beyond reasonable doubt to the satisfaction of a court of law) to have come from 9M-MRO, washed up on la Reunion. It's a long stretch to say that either piece of evidence proves the other or even provides a useful clue to the final resting place of 9M-MRO, other than saying where it probably isn't. I'm reluctant to say never, but it doesn't seem plausible that the only piece of debris found to date could drift past Borneo, Sumatra and/or Java and end up on la Reunion.
