Speaking in Jakarta, the head of Indonesia's
search and rescue agency Bambang Soelistyo
told reporters: "I received information from the
National Transport Safety Committee chief that
at 07:11 (00:11 GMT), we succeeded in bringing
up part of the black box that we call the flight
data recorder."
He said the device was found under the
wreckage of a wing.
Hours later, other officials said the cockpit voice
recorder had also been detected but divers had
not yet managed to reach it.
The two recorders, usually housed inside the
rear part of the plane, are designed to survive a
crash and being submerged in water. They
contain underwater locator beacons which emit
so-called "pings" for at least 30 days.
Supriyadi, operations co-ordinator for Indonesia's
search and rescue agency, said that based on
initial analysis of the wreckage, the plane could
have "exploded" upon landing on the water.
