The French vessel John Lethbridge, which was contracted by the Egyptian government to join the search for the doomed plane, located the cockpit voice recorder about 13,000 feet under sea. The device was damaged but the memory unity, which is considered the most important part, was retrieved and sent to investigators who will conduct an analysis and unload the voice conversations, a spokeswoman for Egypt's Ministry of Civil Aviation said.
France's aviation accident bureau declined to comment.
It's been nearly one month since the Airbus A320 mysteriously crashed in the Mediterranean. The missing EgyptAir plane was en route to Cairo from Paris when it disappeared with 66 people aboard on May 19. According to the company, the flight lost contact with the radar tracking system at 2:45 a.m. at an altitude of 37,000 feet.
Egypt's investigation committee said in a statement Wednesday that the vessel John Lethbridge "had identified several main locations of the wreckage." It added that it obtained images of the wreckage located between the Greek island of Crete and the Egyptian coast.
