Navy device hunts crash jet black boxes
A Dutch ship towing a high-tech, US Navy listening device was trawling the Atlantic today for data and voice recorders that investigators say are key to determining what caused an Air France jet to crash with 228 people on board.
The navy device, called a Towed Pinger Locator, will try to detect emergency audio beacons, or pings, from Flight 447’s black boxes, which could be lying thousands of feet below the ocean surface.
