There was confusion about what happened in the final moments of Flight QZ8501, which crashed off the Indonesian coast on December 28, with one official saying the plane probably exploded before hitting the water and another disputing that theory.
The head of the Indonesian Search and Rescue Agency Fransiskus Bambang Soelistyo announced that the flight data recorder from AirAsia flight QZ8501 has retrieved.
The second so-called black box, containing the cockpit voice recorder, is located about 20 meters away from where the flight data recorder was found, but divers have not yet been able to get to it.
"(The cockpit voice recorder) seems to be under a wing, which is quite heavy," said Supriyadi, operations coordinator for the search and rescue agency. "So we will use air bags to lift it. This will be done tomorrow."
Investigators may need up to a month to get a complete reading of the data.
