Oxygen masks from the missing Air France flight 447 are seen at the Air Force base in Recife June 12, 2009. The French and Brazilian governments said, Friday, they are yet to determine what caused Air France Flight 447 to crash, en route from Rio de Janeiro to Paris on June 1 with 228 people on board, but added that recovery of the bodies and debris from the ocean provide important clues that could help explain what happened during the final moments of the doomed flight.
