Wing walkers perform at the 2016 Royal International Air Tattoo at Royal Air Force Fairford, England. The air show took place from July 8-10, 2016. RIAT 16 afforded an opportunity for new aircraft, like the F-35 Lightning II, to be displayed alongside crowd favorites and provided a weekend of fun and entertainment for the projected 160,000 visitors.
