The cockpit voice recorder from the EgyptAir Airbus that crashed last month has been found in the Mediterranean, according to Egyptian investigators.

The ‘black box’ was damaged and had to be pulled out in several stages, but its memory unit is said to be intact.

A search vessel with an underwater robot has been scouring the crash site and has sent back images of the wreckage.

Flight MS804 from Paris to Cairo crashed on May 19, killing all 66 people on board.

It is not yet clear what caused the aircraft to plunge into the sea.

Investigators said: “The vessel’s equipment was able to salvage the part [of the recorder] that contains the memory unit, which is considered the most important part of the recording device.”

The recorder will now be taken to the Egyptian city of Alexandria to be studied, the BBC reported.

The cockpit voice recorder should allow investigators to hear what the pilot and co-pilot were saying to each other, plus any alarms in the background.
