Missing plane: 'Pings' pinpointed last location

The missing flight MH370 crashed in the southern Indian Ocean, according to Malaysia's Prime Minister Najib Razak.

Airline pilot, Peter Benn, said finding some of the wreckage could help explain what happened to the plane.

"It is a phenomenal piece of work...to triangulate the so-called pings... to actually pinpoint roughly where the aircraft was last heard from," he said.
