A British tabloid has thrown a new wrinkle into the disappearance of Malaysian Airlines Flight MH370. It came after "twisted debris" was been found off the coast of Mozambique.

Tour operator Jean Viljoen told the Sun that he discovered a one metre by one metre piece of a panel that appears to be from an airplance. Viljoen turned it over to police.

There's no confirmation that it's from the missing plane.

But that didn't stop the Rupert Murdoch-owned paper from running the following headline: "Did jet explode? Debris 'from MH370' found off Mozambique coast suggests an EXPLOSION not pilot error caused crash".

The Boeing 777 vanished on its way to Beijing on March 8, 2014, prompting an extensive international search.

This month, Canadian flight-crash investigator Larry Vance has given interviews to the Telegraph and Der Spiegel, arguing that a rogue pilot deliberately flew the plane into the sea.

Vance based this on severe damage to one of the plane's flaperons—high-lift devices—along the trailing edges but not on the leading edges.

"The flaps were extended when the aircraft hit the water," Vance told Der Spiegel. "The trailing edge was dragged over water for some time—some seconds—to erode the trailing edges of those pieces. This evidence is easy to read."

He said that this meant that the flaperons were extended, which could only have been done in the cockpit. And only an experienced pilot could have landed a Boeing 777 on the water like this.

"Somebody wanted that airplane to land on the surface of the ocean in such a way that the fuselage stayed intact, so that everything would go to the bottom, never to be found or seen again," Vance added. "All this talk of this being aviation's biggest mystery makes me angry. There is absolutely no mystery to what happened."
