French investigators release report on Flight 447     By Otavio de Souza (AP)

French investigators on Thursday will present their initial findings into what caused Air France Flight 447 to drop out of the sky in the middle of the Atlantic a month ago, prompting one of history's most challenging plane crash investigations.

The Airbus A330-200 plane flying from Rio de Janeiro to Paris went down with 228 people on board in a remote area of the Atlantic, 930 miles (1,500 kilometers) off Brazil's mainland and far from radar coverage.

A burst of automated messages emitted by the plane before it fell gave rescuers only a vague location to begin their search, which has failed to locate the plane's black boxes. The chances of finding the flight recorders are falling as the signals they emit fade. Without them, the full causes of the tragic accident may never be known.

The French air accident investigation agency, the BEA, will present its preliminary report to journalists at its headquarters in Le Bourget, outside Paris.   Read More...
