*UPDATE*
Up until today, March 10, 2014, it has been reported that there were two people got on board with fake passports. Suspected to be terrorists, but this would remain mystery until the plane is found.
Another news reported the aircraft had changed direction back to KL but still no clue about its position, whether it was crashed, hijacked or--against all odds--jumped to another dimension such as rabbit hole. Who knows?
