Investigators have recovered the cockpit voice recorder (CVR) from the crashed Air India flight, a key step in uncovering what caused last week's deadly accident.

Investigators in India are studying the black boxes of a Boeing 787 Dreamliner after recovering them from the aircraft wreckage to ascertain the cause of last week’s plane crash that left at least 270 people dead.

As part of ongoing investigations, the plane’s black boxes are being analysed. A black box records flight data, and includes a cockpit voice recorder for pilot exchanges and cockpit sounds. It will also pick up engine sounds. Today (Monday 16th) it’s been reported the cockpit recordings have been found.
