This C-54 served as US Navy R5D-4R Bu90407 from 1945 until 1971. After storage at MASDC it went through many owners, as N67038 since 1975 and as N51848 since 1978. It was first seen at the museum in Feb 1992. In early 1998 it was restored in these Military Air Transport Service (MATS) markings, with "US Navy" and "Pacific Division" titles and its authentic serial 90407 on the tail. The Military Air Transport Service was formed in 1948 out of the US Navy's Naval Air Transport Service (NATS) and the USAF's Air Transport Command (ATC). It was discontinued in 1966.
