00:02 'Mechanical failure likely behind the crash'
The BBC's Transport Correspondent Richard Westcott says it seems most likely mechanical failure was behind the crash.

Dr Paul Williams, atmospheric scientist at the University of Reading, says it is unlikely weather conditions will have played a part in the crash, based on the information currently available. He said there was "some light clear air turbulence forecast" on the flight route but "nothing out of the ordinary... nothing that a modern airliner couldn't normally cope with", the BBC reported.
