Lieutenant Colonel Jeffrey S. Feinstein was a career officer in the United States Air Force. In 1972 during the Vietnam War, while flying as a weapon systems officer aboard F-4 Phantom IIs, Feinstein downed five enemy aircraft, thereby becoming a flying ace, the last of five U.S. aviators to become aces during that conflict. Born in Chicago, Illinois on January 29, 1945, Feinstein enlisted in the Air Force in 1963 to attend the United States Military Academy Preparatory School. He subsequently entered the United States Air Force Academy in 1964 and graduated in 1968. His actions, for which he received multiple awards of the Distinguished Flying Cross and Silver Star for his first four kills and the Air Force Cross for his fifth kill, took place prior to and during Operation Linebacker in 1972 while Feinstein, assigned to the 80th TFS, was detached to the 13th Tactical Fighter Squadron, part of the 432d Tactical Reconnaissance Wing, based at Udorn Royal Thai Air Force Base, Thailand. His nickname/tactical callsign was "Fang."
