In this Monday, June 8, 2009 file photo released by Brazil's Air Force, Brazil's Navy sailors recover debris from the missing Air France Flight 447 in the Atlantic Ocean. Undersea robots have located a "large part" of an Air France jet that plunged into the Atlantic Ocean in 2009, but haven't yet found its black box flight recorders, French officials said Monday April 4, 2011. Victims' families cautiously welcomed the surprise announcement that search teams have located pieces of the plane, after nearly two years of fruitless efforts to determine what caused it to crash. Investigators have said without the recorders, the cause may never be determined.
