EgyptAir plane's black box signals detected by French ship

A French company has confirmed that its special undersea search ship has detected signals from one of the black box flight recorders on the EgyptAir flight that crashed into the Mediterranean Sea last month.

Alseamar said the Laplace ship started searching for the signals at midday on Tuesday, and "less than 24 hours were necessary ... to locate signals from a detector attached to one of the recorders of flight MS804".

The French air accident investigation agency BEA said it is impossible to determine from the signals whether it is the flight's data or voice recorder.

All 66 passengers and crew on board the flight were killed when the plane crashed on May 19.

The development has raised hopes the plane's flight data and cockpit voice recorders, known as the black boxes, could be retrieved and shed light on the aircraft's crash.

Egyptian officials said a second ship, John Lethbridge, affiliated with the Deep Ocean Search firm, will join the search team later this week.

Locator pings emitted by flight data and cockpit voice recorders, known as the black boxes, can be picked up from deep under water. The Laplace is equipped with three detectors designed to detect and localise signals from the flight recorders, which are believed to be at a depth of about 3,000 metres under water. By comparison, the wreck of the RMS Titanic is lying at a depth of about 3,800 metres.

Shaker Kelada, an EgyptAir official who has led other crash investigations for the carrier, said half "the job has been done now" and that the next step would be to determine the black boxes' exact location and extract them from the sea.

"We have to find where the boxes are exactly and decide on how to pull them out," he said, adding that search teams might need to send in robots or submarines and "be extremely careful ... to avoid any possible damage".

Mr Kelada said he was confident the boxes will be retrieved. He had investigated the Flash Airlines Flight 604 crash in 2004, when the aircraft hit the Red Sea shortly after take-off from the resort of Sharm el-Sheikh, killing all 148 passengers, most of them French tourists, and crew on board.

In the May 19 crash, EgyptAir Airbus A320 had been cruising normally in clear skies on a nighttime flight to from Paris to Cairo when it suddenly lurched left, then right, spinning all the way around and plummeting 38,000 feet into the sea, Greek Defence Minister Panos Kammenos said shortly after the crash.

However, Egyptian officials refuted this, saying the plane did not swerve or lose altitude before it disappeared off radar. A distress signal was never issued, EgyptAir has said.

Since the crash, small pieces of the wreckage and human remains have been recovered while the bulk of the plane and the bodies of the passengers are believed to be deep under the sea. A Cairo forensic team has received the human remains and is carrying DNA tests to identify the victims. The search has narrowed down to a 3-mile area in the Mediterranean.

David Learmount, a consulting editor at the aviation news website Flightglobal, said the black boxes' batteries can transmit signals up to 30 days after the crash. But even if the batteries expire, locating the boxes remains a possibility.

"It's terribly important to find the black boxes, because if they don't find them, they will know nothing about the aircraft," he said, citing the 2009 Air France Flight 447 crash in the Atlantic Ocean, when black boxes were found two years later.

Nearly two weeks after the crash off Egypt's northern coast, the cause of the tragedy has still not been determined. Egypt's civil aviation minister, Sherif Fathi, has said he believes terrorism is a more likely explanation than equipment failure or some other catastrophic event.

But no hard evidence has emerged on the cause, and no militant group has claimed to have downed the jet. Earlier, leaked flight data indicated a sensor had detected smoke in a lavatory and a fault in two of the plane's cockpit windows in the final moments of the flight.

Safety on board Egyptian aircraft and at the country's airports has been under close international scrutiny since a Russian airliner crashed in the Sinai Peninsula last October, killing all 224 people on board, shortly after taking off from an Egyptian resort.

That crash - claimed by the Islamic State's affiliate in Sinai and blamed by Moscow on an explosive device planted on board - decimated Egypt's lucrative tourism industry, which had already been battered by years of turmoil in the country.

Also on Wednesday, Egyptian authorities reported that they had evacuated all passengers from the EgyptAir Flight 960 from Cairo to Bangkok scheduled late the previous night after receiving security threats of a bomb on board.

Tarek Zaki, head of security at Cairo airport, said the warning claimed an unidentified assailant had planted a bomb on the plane. A security official said the plane and the bags were searched but no bomb was found. The threat caused a delay and eventually led to the flight being cancelled.
