Investigators receive black box data from plane that crashed in Kazakhstan

Authorities now have access to cockpit dialogue from Azerbaijan Airlines plane that went down on Christmas Day

Brazil's air force has extracted the data from two black box recorders belonging to a crashed Azerbaijan Airlines plane that Baku claims was downed by Russia on Christmas Day, killing 38 of the 67 people on board.

The Brazilian-made Embraer 190 crash-landed in Kazakhstan after being diverted from a scheduled landing in the Chechen capital, Grozny, in southern Russia. Azerbaijan believes the plane was shot down by Russian air defences, which Moscow says were operational in the area at the time.
