All smiles as divers locate crucial second black box which will reveal final words of pilots.

There was joy and elation after a team of navy divers earlier on Monday retrieved the flight data recorder from the wreckage. Divers have also found the second black box, but they have not yet been able to free it from debris on the floor of the Java Sea. Mr Supriyadi confirmed the cockpit voice recorder was located on Monday just hours after officials announced that the other black box - the data flight recorder - had been brought to the surface.

He said the second black box was stuck under heavy wreckage, and divers are now working to lift it. 

The flight recorder monitors data such as airspeed and the aircraft's heading, while the cockpit voice recorder stores radio transmissions and sounds from within the cockpit.
