In 1972, Captain Steve Ritchie shot down 5 Mig 21s to become the only USAF pilot ace of the Vietnam War. Ritchie fittingly flew this F-4E, specially painted in Vietnam era markings, at the USAF 50th anniversary Airshow at Nellis AFB in April 1997. This Phantom was one of two painted for this occasion as Steve Ritchie's Vietnam Mig Killer, which actually was 66-7463 for three kills and has been withdrawn from service long before.
