The first Skyfox converted was an ex-
Canadian Forces Canadair CT-133 Silver Star (the Canadian license-built variant of the T-33) which was formerly a Silver Star 3AT (Armament Trainer). This particular aircraft, produced in 1958, had construction number T.33–160 and serial number RCAF 21160. It was struck off charge on 10 November 1970 and was sold through
Crown Assets Disposal Corporation to Leroy Penhall/Fighter Imports in 1973. It was then sold to Murray McCormick Aerial Surveys in 1975. Its next owner was Consolidated Leasing in 1977. After conversion to the Skyfox configuration it flew its first flight as the Skyfox prototype on 23 August 1983, nearly 35.5 years after the first flight of the T-33. Race and test pilot
Skip Holm performed the initial flight test at the
Mojave Airport, California. The Skyfox prototype was white overall, with black cheat lines, and a very pale blue trim. The Skyfox Corporation was not able to find any buyers for the aircraft, despite its price and capability. However, in 1986, Boeing Military Aircraft Company saw potential, and purchased the marketing and production rights. Even though
Portugal signed a letter of intent for 20 conversion kits, no other nation signed on, and faced with a lack of customers, Boeing cancelled the project. The prototype aircraft remains the only Skyfox built. For over two decades, the prototype was parked on the flightline at
Rogue Valley International-Medford Airport in
Medford, Oregon without engines or cowlings. In 2021, the aircraft was acquired and restored to static display condition, and as of 2024 is on display at the
Palm Springs Air Museum in
Palm Springs, California. ==Specifications==
