A French vessel, Laplace, picked up signals from one of the black boxes from EgyptAir Flight 804, prompting authorities to narrow down the search operation within a zone of 2km to 5km in the Mediterranean Sea.
The recovery of the black boxes is crucial to find out why the Airbus A320 with 66 people on board crashed en route from Paris to Cairo on May 19.
A statement released by the Egyptian ministry said that a second ship, the John Lethbridge, will join the search operation, writes The Guardian. The Lethbridge is equipped with a robot that can retrieve black boxes by diving up to a depth of 3,000 meters.
Amid speculation that a terrorist attack may have brought down the aircraft, investigators have been sweeping through the Mediterranean to find evidence that could lead to cause of the incident. So far, search teams have found small pieces of the wreckage in addition to some human remains, which have been dispatched for forensic analysis.
As the investigators narrowed down the search zone, France's Transport Minister Alain Vidalies said that the black boxes would be recovered from the seabed in about eight days.
