Members of the U.S. Army Golden Knights Parachute Team perform a demonstration June 13, 2015, during the Wings Over Whiteman air show at Whiteman Air Force Base, Mo. The 24 demonstrator positions on the team are typically held for at least three consecutive years. At the end of their tenure, soldiers will then either rotate back to Army units or they may request to stay with the team for an additional period of time. (U.S. Air Force photo by Staff Sgt.
