"The CVR is badly damaged and burned down," Daryatmo said at Halim Perdanakusuma airport in Jakarta Wednesday.
Daryatmo arrived at Halim from Bogor with the black box by two military helicopters. The black box has been retrieved by the joint SAR team yesterday afternoon and was brought to the Cijeruk command post seven hours later.
He said while its condition is burned down, the component could still be used because it was burned down only externally.
"The one that has not been recovered is the Flight Data Recorder (FDR), and the team was still searching for it," Daryatmo.
