This T-33 spent its entire USAF career in various Air Defense Command (ADC) squadrons. It was used for instrument proficiency flying, and each ADC squadron had a T-33 assigned to it. It is still in the markings of the 13th Fighter Interceptor Squadron, its last unit. The museum acquired the a/c in 1981 from a city park in Vborg, S.D. It was in derelict condition, having been vandalized, with holes in the fuselage and other damage. Another wonderful restoration by the museum.
