Investigators have identified two giant arcs of territory spanning the possible positions of the plane about 7½ hours after takeoff, based on its last faint signal to a satellite — an hourly “handshake” signal that continues even when communications are switched off. The arcs stretch up as far as Kazakhstan in central Asia and down deep into the southern Indian Ocean.
Police are considering the possibility of hijacking, sabotage, terrorism or issues related to the mental health of the pilots or anyone else on board, and have asked for background checks from abroad on all foreign passengers.
Hishammuddin said such checks have been received for all the foreigners except those from Ukraine and Russia — which account for three passengers. “So far, no information of significance on any passengers has been found,” he said.
The 53-year-old pilot joined Malaysia Airlines in 1981 and had more than 18,000 hours of flight experience. People who knew Zaharie from his involvement in opposition political circles in Malaysia and other areas of his life have described him as sociable, humble, caring and dedicated to his job.
The crisis has exposed the lack of a failsafe way of tracking modern passenger planes on which data transmission systems and transponders — which make them visible to civilian radar — have been severed. At enormous cost, 26 countries are helping Malaysia look for the plane.
Relatives of passengers on the missing airliner — two-thirds of them from China — have grown increasingly angry over the lack of progress in the search. Planes sweeping vast expanses of the Indian Ocean and satellites peering on Central Asia have turned up no new clues.
At a hotel near the Kuala Lumpur airport, one of the Chinese women who was removed from the room displayed a banner that said, in part, “We are against the Malaysian government for hiding the truth.” She later expressed frustration with officials.
