Family and friends of Col. Steven Hiss, 28th Bomb Wing vice commander, spray him with a water hose and champagne after his final B-1 flight at Ellsworth Air Force Base, S.D., June 7,2012. After 26 years of flying airplanes, the moment was bittersweet as Hiss was congratulated and thanked by family and friends after stepping down from a B-1 for the last time.
