A reported sighting of the Airways Aero Association D.H.Dragon G-ACIT by Air Britain member David Munkenbeck at Heston around September 1950, seems to indicate that an executive or representatives of the Association flew in from Denham in order to prearrange landing rights with the Ministry of Civil Aviation, Heston for aircraft from Denham to attend the future B.O.A.C. Sports Festival and allow flying possibilities for sightseeing.
Since the airfield had been officially closed since 1947, this was a very necessary requirement and would have involved some special arrangements and insurance cover no doubt.
