Egypt's Civil Aviation Ministry said Wednesday, June 1, 2016 that a French ship has picked up signals from deep under Mediterranean Sea, presumed to be from black boxes of the EgyptAir Airbus A320 with the registration SU-GCC that crashed last month, killing all 66 passengers and crew on board. The Civil Aviation Ministry is citing a statement from the committee investigating the crash as saying the vessel Laplace is the one that received the signals. It says that a second ship, John Lethbridge affiliated with the Deep Ocean Search firm, will join the search team later this week.
