I idly watched a bit of the annual showing of the 1969 BofB film, but could take no more when two converted Percival Proctors playing at Stukas, and radio-controlled Stuka models, were shown glide-bombing the Ventnor Chain Home facility with unerring accuracy and to the noise of sirens and without swing-down bomb cradles.

There were many Germans in the cast, even speaking German to each other, and many obvious efforts had been made to achieve accuracy, going as far as destroying a WWII hangar at Duxford, but I've resigned myself never to seeing a realistic vertical Stuka attack portrayed on film.
Why is that, I wonder?
