He said the flight data recorder was found under the wreckage of a wing some distance from the main crash locus. This seems to confirm Julian Brays earlier suggestion the aircraft entered the water at high velocity possibly spinning and broke up on impact with the sea.
A few hours later, it was reported the second part of the data system the cockpit voice recorder had also been detected but divers had not yet managed to reach it.Indonesia's search and rescue agency, suggested that based on initial analysis of the wreckage, the plane could have "exploded" upon landing on the water.
The two recorders, some 30 metres under the sea, in this case confirmed by the airline owner as being housed near the tail section, are solid state and designed to survive a crash, fire and being immersed in water or other fluids. They also contain underwater locator beacons sending out "pings" every 30 seconds for a minimum of at least 30 days from the inbuilt battery having a shelf life of some six years. Normally experts would expect the recovered units would be kept in a submerged state in a tank of sea water, but early television pictures appear to show at least one of the units still attached to debris and lashed down, secured to the recovery ship aft deck. Later images show the unit has now been transferred to a sealed fresh water filled transit tank.
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. The data from the two recorders will confirm if this is correct.
He told the AFP news agency:"The cabin was pressurised and before the pressure of the cabin could be adjusted, it went down - boom. That explosion was heard in the area,"
