The Beijing-bound jetliner’s transponders were shut off without a mayday call less than an hour into the flight before veering wildly off course while flying over the South China Sea. Aviation experts claim that the aircraft’s movements were consistent with deliberate action and that calculated changes in the flight’s trajectory indicate that the plane was continually under the command of a pilot. Investigators used satellite data from the craft to chart two possible corridors along which the missing plane may have sent out its final communications.
The northern corridor extended from northern Thailand and upward toward the border of Kazakhstan and Turkmenistan while the southern corridor stretched from the western Indonesia to the remote southern Indian Ocean. Investigators have focused their search on the southern corridor, a 60,000 square kilometer patch of the Indian Ocean some 1,800 kilometers west of Perth, Australia. Despite the use of the best available underwater detection technology, the multinational search operation has failed to produce any evidence of the aircraft crashing into the sea.
