Divers in Indonesia recovered one of two black boxes from AirAsia MY:AIRASIA Flight 8501 on Monday, two days after the aircraft’s mangled tail section was pulled from the sea and loaded onto a ship.

Bambang Soelistyo, head of Indonesia’s search-and-rescue agency, said searchers had retrieved the jet’s flight-data recorder at 7:11 a.m. on Monday. They are still searching for the other black box, the cockpit voice recorder, he said.
