The Malaysia Airlines jet vanished on March 8 2014 en route from Kuala Lumpur to Beijing with 239 people aboard. Using satellite data, it was concluded the plane went into the Indian Ocean, but investigators could not find the wreckage in the great expanse of water. Missing planes are usually found by spotting debris on the surface.
This debris can then be used to locate where the main wreckage is on the ocean bed.

“At that point, underwater microphone gear would be towed back and forth listening for acoustic pingers attached to the black boxes."
He added: “All they had to do was find one single piece and in a stroke much of the uncertainty surrounding MH370’s
