French search teams have found one of two data recorders from an Air France flight that crashed off the coast of Brazil nearly two years ago.
The object was photographed before it was pulled to the surface of the Atlantic.
The discovery has revived hopes that what caused the Airbus jet to plunge into the ocean may finally be understood.
All 228 passengers and crew on board were killed in the crash in June 2009. The plane was en route to Paris from Rio de Janeiro.
Investigators have combed thousands of square kilometres of sea floor. The box records cockpit conversations and could give vital clues about the flight’s final moments.
There has been speculation that the plane’s speed sensors iced up in stormy weather.
