Multiple sources are reporting that a part of a wing, likely from a Boeing 777, has been found near a shore along the Indian Ocean.

Investigators say that the piece, now being sent to undergo testing, was found off of Reunion Island.

The big question is whether the wing piece is part of Malaysia Airlines Flight MH-370.  If it is, it would be the first physical evidence retrieved of the plane, which seemingly fell from the sky on March 8, 2014 with 239 people on board.
