Sub recovers Red Sea 'black box'

CAIRO, Egypt (CNN) — An unmanned French Navy “Scorpio” submarine has recovered the flight data recorder from the wreckage of an Egyptian airliner about 1,000 meters under the Red Sea, Egyptian officials said Saturday.

Investigators are hoping the so-called black box will help explain what caused the January 3 crash of the Flash Airlines Boeing 737, which crashed into the sea shortly after take-off from the resort town of Sharm El-Sheikh.
