Excellent film . I lived at RAF Cranwell AMQ 1966/7 many happy hours spent gliding on the North airfield . The shot of all the parked Chipmunks is where the present Aircrew Selection building stands. The hangar used for the raft exercises was full of Chipmunks in 1967. The hangar near to the Italian restaurant(was the Post Office then) was the Glider flight and the Flying Club with Tiger Moths and Austers.
