Taken on strength by the RCAF March 5 1958 with serial 9594, this helicopter was never actually operated by the Air Force. It was one of three Vertol H-21s (9595 / CF-JJW and 9596 / CF-JJX were the other two) loaned to Dominion Helicopters for construction of the Mid-Canada Line. This was a system of cold war radar stations stretching east to west across the middle of Canada. Returned to the RCAF in September 1965 all three helicopters were held in reserve for Air Force Rescue squadrons until stored at Mountainview in 1969. CF-JJV was struck off strength in March 1971.

Landing at some sort of event. An aerial photographer with the USAAF during WWII, Gerald Massie became Missouri's official state photographer from 1945 and continued to take promotional photos until 1974. The helicopter also had a long active career, from 1955 until 1979. It is preserved at Little Rock AFB since 2016. Photo by: Gerald Massie / Missouri State Archives
