AirAsia, which has a presence in most of Southeast Asia and recently India, has never lost a plane before and has a good safety track record.
“We don’t dare to presume what has happened except that it has lost contact.” Djoko Murjatmodjo, Indonesia’s acting director general of transportation, told reporters. He said the last communication between the pilot and air traffic control was at 6.13 a.m. (2313 GMT Saturday) when the pilot “asked to avoid clouds by turning left and going higher to 34,000 feet.”
He said there was no distress signal from the cockpit.
The contact was lost about 42 minutes after the single-aisle, twin-engine jetliner took off from Surabaya airport, Hadi Mustofa, an official of the transportation ministry told Indonesia’s MetroTV. It was about an hour before it was scheduled to land in Singapore at 0030gmt.
The plane had two pilots, five cabin crew and 155 passengers, including 16 children and one infant, AirAsiaIndonesia said in a statement. Indonesian officials had earlier said there were 161 people on board.
The AirAsia statement said there were six foreigners on board— three South Koreans and one each from Singapore, Malaysia and France. The rest were Indonesians.
