U.S. Army Pfc. Jackie Enchautegui, from the 689th Rapid Port Opening Element, measures a Humvee parked inside the Small Air Terminal at Langley Air Force Base, Va., during a joint training exercise, Nov. 19, 2013. Soldiers measured and weighed the vehicle to determine the precise balance point and position it would need to occupy aboard an aircraft. (U.S. Air Force photo by Staff Sgt. Jarad A. Denton/Released)
