An F-35 Lightning II helmet sits on stage during the F-35 reaching initial operational capability panel discussion during the Air Force Association's Air, Space and Cyber Conference in National Harbor, Md., Sept. 20, 2016. The F-35’s helmet mounted display system is the most advanced system of its kind. All the intelligence and targeting information an F-35 pilot needs to complete the mission is displayed on the helmet’s visor. (U.S. Air Force photo/Tech. Sgt. Anthony Nelson Jr.)
