Indonesian divers retrieved the battered casing of the cockpit voice recorder from the Sriwijaya Air jet that plunged into the Java Sea on January 9, but not the crucial memory unit containing its data.
The computer chips that store a recording of pilot communications and ambient sounds in the cockpit broke loose from the so-called black box’s exterior, the Indonesian authorities said.
The Boeing Co 737-500 dove steeply about four minutes after takeoff, slamming into the sea at an apparent high rate of speed, according to Flightradar24 tracking data.
Underwater locater beacons attached to both crash-proof black boxes became dislodged in the impact. The flight-data recorder was found earlier.
