Let’s get back to the facts. On March 8, 2014, the flight from Kuala Lumpur to Beijing disappeared from radar screens fifty minutes after takeoff, as it entered Vietnamese airspace. The means of communication were cut off. It is found a few days later, thanks to satellite data, that the plane would have changed course over the Indian Ocean and then continued to fly for several hours. If a military radar tracked it after it ceased to emit, its trace is definitively lost to the northwest of the island of Penang, in the Strait of Malacca.
The passengers were declared dead by Malaysian authorities on March 24, 2014 and despite four years of searching, they were never found. In 2015 and 2016, debris was discovered in the Indian Ocean, stranded for example on a beach on Reunion Island, and was identified as belonging to the Boeing 777. No theory is favored today. According to the Malaysian authorities report of 2018, only two theses are not to be excluded : a hijacking of the aircraft by someone on board or a series of incidents that caused the crash. That of a suicide of the pilot, long favoured, is ruled out.
