I remember my Dad taking us to Bovingdon in what must have been the late sixties. A whole bunch of a/c had flown in, one of which was an orangey/red thing, a bit like a Lanc as I remember, and my Dad told me that a camerman fell out of it, obviously, to his untimely death !!.
Incidently, XV490, you will obviously know 'The Swan' in Ley Hill. Did you know that the pub scenes in 633 Squadron were filmed there ?
Anyway, now I live in Chesham, just down the road from Bovingdon. A lot of Chesham girls ended up moving to the USA, because Chesham was the main town where the 8th Airforce boys spent their dosh.
I fly out of Denham, and generally return there via Bovingdon thanks to it's VOR. Many others use it too, and on a saturday or sunday when the weather's good aircraft are like the proverbial flies round a cows a*se, so I always transit the area at an irregular altitude. (Not that I can hold regular one !!!!!!)
