Ex XP447. Built as an Argosy C.1 and converted to a T.2 in 1974, still wearing the name 'Horatious' given when operating with 215 Squadron. Registered N1430Z in 1976 with Management Jets International to operate a contract for the Alaska Bureau of Land Management. Withdrawn from use in 1991 and displayed, initially at the Museum of Flying in Santa Monica and later the Milestones of Flight Museum at Lancaster, Fox Field CA. That museum closed in 2015 but the Argosy remains stored there at time of upload.

Airfreight operation on behalf of the West-German company Orbital Transport und Raketen AG (OTRAG), to support the construction of a missile launch facility in Zaïre. OTRAG was formed in 1975 to develop and operate a low cost satellite launch vehicle, using an alternative propulsion system for rockets suitable for inexpensive mass-production. As such, the company was the first commercial developer and producer of space launch vehicles. They built a test and launch facility in Shaba, Zaire (near the equator), and the first test launch from the site took place on 17 May 1977. However, a full orbital launch vehicle was never assembled and the project ceased in the early 1980s.

In use as a training airframe for engineering apprentices.
