An official says Egyptian investigators have started analyzing the cockpit voice recorder from an EgyptAir plane that crashed in the Mediterranean Sea last month, killing all 66 people on board.

The official with the committee said Friday that investigators have started processing the recorder, which arrived in Cairo overnight from the crash site. The official could not be named because they were not authorized to brief the media.

The EgyptAir Airbus A320 was en route to Cairo from Paris when it crashed on May 19 between the Greek island of Crete and the Egyptian coast.

Officials say the so called "black box" — one of the two on board the plane — has been damaged but that the vessel searching for the wreckage managed to safely recover the memory unit.
