At 02:40 local time on Saturday (18:40 GMT on Friday) Malaysia Airlines confirmed that they had lost the aircraft and all communication and radar contact was lost with the aircraft over the airspace controlled by Vietnam (with early speculation).
It has been reported that the flight was lost two hours after taking off from Kuala Lumpur. It was confirmed by the Chinese state news agency Xinhua that it has not entered Chinese airspace as expected.
Currently, it is unknown whether the aircraft has crashed or whether there are communication problems onboard the aircraft making it impossible to track by radar or air traffic control. If communication had failed on the aircraft, it's possible to track it using basic radar services however no IDENT code would be supplied.
The Malaysia Airlines Boeing 777-200 was carrying 227 passengers in total which included twelve crew members and two children. It was flying from Kuala Lumpur to Beijing on a routine flight and regular flight and path.
As far as we can see, search and rescue services are being deployed in the area to search for the aircraft at its last known location, however the search area could be large and take some time to cover.
From research, it appears that flight MH370 was performed by a Boeing 777-2H6 (9M-MRO). It was also stated that the aircraft was almost 12 years old.
This would be one of the most significant losses for a Boeing 777 (if the aircraft has been lost) with currently an amazing safety record and history of service.
If you are affected by this or have family members on the flight and would like further information and support, Malaysia Airlines have set up an emergency support telephone line that can be reached on +603 7884 1234. For media queries, contact +603 8777 5698/ +603 8787 1276.
Update 02:14 GMT:
There have been unconfirmed reports that the aircraft may have landed in Nanning, China. This is unlikely as we would have known about this by now but we thought we'd post that update for reference.
More updates to follow.
