MH370: Could wreckage found in Reunion be from missing plane?

French officials are investigating whether plane wreckage that washed up on an Indian Ocean island is from missing flight MH370.

The debris, apparently a wing flap, was found on French-owned Reunion.

An aviation security expert said it had "incredible similarities" to a flap from a Boeing 777, the type of plane that vanished in March 2014.

But the island is a huge distance from the plane's search area and there have been other crashes much closer.
