The probable fourth hull loss occurred on March 8, 2014, when a 777-200ER carrying 227 passengers and 12 crew, en route from Kuala Lumpur to Beijing as Malaysia Airlines Flight 370, was reported missing. Air Traffic Control's last reported coordinates for the aircraft were over the South China Sea. After the search for the aircraft began, Malaysia's prime minister announced on March 24, 2014, that after analysis of new satellite data it was now to be assumed "beyond reasonable doubt" that the aircraft had crashed in the Indian Ocean and there were no survivors. The cause remains unknown, but the Malaysian Government in January 2015, declared it an accident. US officials believe the most likely explanation to be that someone in the cockpit of Flight 370 re-programmed the aircraft's autopilot to travel south across the Indian Ocean. On July 29, 2015, an item later identified as a flaperon strongly suspected to be from the missing aircraft was found on the island of Réunion in the western Indian Ocean.
