“It’s a remote location far from any possible landing sites, it is therefore with deep regret I inform you that according to new data MS 370 ended in the southern Indian Ocean,” said Malaysian Prime Minister Najib Razak.

Malaysian flight 370 was supposed to be heading to Beijing on March 8th, but instead vanished from radar screens less than an hour after takeoff from the airport in Kuala Lumpur.

Investigators believe someone on board may have shut off the plane’s communication systems.

Military radar tracking shows the plane turned west, off of its original flight path, suggesting it was under the control of a skilled pilot.
