A second day of searching for the vanished AirAsia plane with 162 people on board ended Monday, with the head of Indonesia's search and rescue service saying the Airbus A320-200 was likely "at the bottom of the sea." There was still no sign of AirAsia Indonesia flight 8501, which disappeared from radar over the Java Sea after taking off from Surabaya in East Java en route to Singapore on Sunday morning, dpa reported. "We did not find any parts or debris of the aircraft," said Bambang Sulistyo, the head of the National Search and Rescue Agency. He said that based on the last known radar coordinates, the jet likely crashed into the ocean.
