A former pilot has shared his theory of what really happened to the missing Malaysia Airlines flight MH370. A total of 239 passengers and crew were aboard the Boeing 777 when it disappeared on 8 March 2014. While governments stopped their official search for the aircraft in 2017, experts in the aviation industry continue to look for answers. In BBC documentary Why Planes Vanish: The Hunt for MH370, Jean Luc Marchand, former air traffic manager at Eurocontrol and retired commercial pilot Captain Patrick Belly, say they are convinced the plane was steered off-course by an experienced pilot.

The Boeing 777 with 239 people on board vanished in 2014 in one of the greatest aviation mysteries.
