On July 14, 1966, Duane Buttell, Jr., was the "Guy in Back" of an F-4 fighter escorting F-105s to a target over North Vietnam. Suddenly, several enemy MiG-21s appeared. Buttell and his co-pilot, William Swendner, shot down the MiG in one of the first victories over that aircraft during the Vietnam War. The aerial battle made such an impact that Hanoi Hannah mentioned Duane by name on a subsequent broadcast.
