AirAsia flight QZ8501: First video of 'black box'

Indonesian divers have retrieved the flight data recorder of crashed AirAsia Flight QZ8501, say officials.

They believe they have also located the cockpit voice recorder, the second part of the so-called black box, but divers have not yet managed to reach it.

AirAsia flight QZ8501 disappeared in bad weather on 28 December with 162 people on board.

The BBC's Karishma Vaswani said discovery of the 'black box' was a "vital part of the recovery process".
