I donate the second of the prototypes to Aeroventure, or South Yorks Aircraft Museum in Doncaster based on the site of the historic airfield... a place where, for instance, all of the wartime DC-3 Dakotas were modified for use by the RAF (to right-hand drive?).
For me though in the late 1970s it was a place beside the race-course that the crew-bus passed by enroute to Finningley. Each airfield was established by the Royal Flying Corps in WW1 and are thus amongst the oldest in the UK, if not Europe. On a more modest scale altogether it was where I first took to the skies myself: at the controls of the venerable Bulldog and alongside Squadron Leader and Spitfire pilot, Ron Brown.
Like so many exhibits this is a sum of its parts, its duplicate in the Helicopter Museum bearing the original airframe, and this the motors and propellers used in that test-flight of December last year. I like the fact it hangs here from the ceiling, and in the very best of company in the form of Bell's 47.
