Mystery continues to surround the fate of Malaysia Airlines flight MH370, which disappeared without trace more than a week ago.
The Boeing 777-200ER plane, with 239 people on board, vanished from air traffic control screens at approximately 01:20 local time on Saturday 8 March – just an hour after leaving Kuala Lumpur bound for Beijing.
Concrete facts about what happened remain elusive. A variety of theories have been put forward, from hijacking or sabotage, to a slow loss of cabin pressure, which in turn could cause the crew and passengers to become disorientated.
But, with no debris yet identified, much of the search has been focused on the last-known movements of the aircraft.
So, how do you track a plane and what do we know about the movements of flight MH370?
