Egypt is using a robot submarine to help search for debris from the crashed EgyptAir flight

Egypt has sent a robot submarine to join the hunt for an EgyptAir plane which crashed in some of the deepest waters of the Mediterranean Sea with 66 people on board, President Abdel Fattah al-Sisi said on Sunday.


Ships and planes scouring the sea north of Alexandria have found body parts, personal belongings and debris from the Airbus 320, but are still trying to locate the black box recorders that could shed light on the cause of Thursday's crash.


Sisi said that underwater equipment from Egypt's offshore oil industry was being brought in to help the search.


"They have a submarine that can reach 3,000 meters under water," he said in a televised speech. "It moved today in the direction of the plane crash site because we are working hard to salvage the black boxes."


An oil ministry source said Sisi was referring to a robot submarine used mostly to maintain offshore oil rigs, Business Insider reports. It was not clear whether the vessel would be able to help locate the black boxes, or would be used in later stages of the operation.


Air crash investigation experts say the search teams have around 30 days to listen for pings sent out once every second from beacons attached to the two black boxes. At this stage of the search they would typically use acoustic hydrophones, bringing in more advanced robots later to scan the seabed and retrieve any objects once they have been found.


EgyptAir flight 804 from Paris to Cairo vanished off radar screens early on Thursday as it entered Egyptian airspace over the Mediterranean. The 10 crew and 56 passengers included 30 Egyptian and 15 French nationals.


French investigators say that the plane sent a series of warnings indicating that smoke had been detected on board shortly before it disappeared.
