Spartan aircraft were often seen in the UK during the 1960s and 70s as they plied their way from Canada to the third world and back on survey contracts. This C-47 was acquired in 1956 and served until 1969 when it became N19721. The aircraft was seen as such at Winnipeg (CYWG) in October 1973, still carrying the same roof antennae but with a birdie (or 'bomb') under the belly instead of the radome used here.
