The French naval search vessel Laplace detected signals originating from one of the black boxes of EgyptAir flight MS804, Egyptian and French investigators said, according to Reuters. “The search for the black boxes was intensifying ahead of the expected arrival within a week of another vessel, the John Lethbridge, from Mauritius-based company Deep Ocean Search to help retrieve the devices,” the committee reportedly said. “Laplace identified the signals that ‘might belong to one of the data recorders’ from the EgyptAir flight, said France’s BEA, who are responsible for investigating air incidents,” BBC reported.
