Here is a timeline of events in the disappearance of a Malaysia Airlines jetliner which vanished from radar screens on a flight from Kuala Lumpur to Beijing on Saturday, March 8.

 

12.41am: Malaysia Airlines Flight MH370 departs from Kuala Lumpur International Airport and is due to land in Beijing at 6.30am the same day. On board the Boeing 777-200ER are 227 passengers and 12 crew.

 

1.07am: After take-off and ascent, the plane sends its last Aircraft Communications Addressing and Reporting System (Acars) transmission, which gives engine maintenance data to the ground. The system is later deactivated at an unknown time.

 

1.19am: Someone in the cockpit says "All right, good night" to Malaysian air traffic control. They were the last words heard from Flight MH370.

 

1.21am: The plane drops off air traffic control screens as its transponder - which responds to civilian radar - is switched

off. The Civil Aviation Authority of Vietnam says the plane failed to check in as scheduled at 1.21am with air traffic control

in Ho Chi Minh City. 

 

Malaysian authorities believe that someone on board shut off the plane's communications systems and turned it sharply to the west.

 

2.14am: Malaysian military radar plots Flight MH370 at a point south of Phuket island in the Strait of Malacca, hundreds of miles west of its last known location.

 

8.11am: The last signal received from the plane, according to satellite tracking data. The final communication placed the

plane somewhere in one of two corridors: a northern arc stretching from northern Thailand to Kazakhstan, or a southern one stretching from Indonesia to the vast southern Indian Ocean.
