MH370 MYSTERY.

DAN HARRIS (ABC NEWS) (Off-camera) This is not a problem that's going away any time soon, Marci, thank you. Now, thought, to the story we mentioned at the top of the show, there it is, that piece of an airplane wing found on an island off the coast of Africa. It has just now arrived in France for analysis. There's growing certainty that it is, in fact, from the Malaysian airliner that went missing 16 months ago, so the question is could it hold clues as to why that plane disappeared without a trace? We get more now from ABC's Bob Woodruff in Beijing. Bob, good morning. [ABSTRACT FROM PUBLISHER]
