U.S. troops parachute out of a C-17 plane flying over Maniago, near the NATO airbase of Aviano, Italy, during an exercise, Tuesday, March 22, 2011. An American fighter jet crashed over North African country, both crew ejecting safely. The U.S. Africa Command said both crew members were safe after what was believed to be a mechanical failure of the Air Force F-15. The aircraft, based out of Royal Air Force Lakenheath, England, was flying out of Italy's Aviano Air Base in support of Operation Odyssey Dawn. (AP Photo/Luca Bruno)
