A mate of mine got involved in a strange film about mosquitos in the early 1970s. IIRC it was a Dutch (??) TV film which was filmed in and around Stanford PTA, with full MoD backing. The only "mosquito" was a ginormous r/c model, and air-to-air shots were filmed from matie's Puma!
It can't have been that accurate a film, cos they also used night internal shots of the Puma cockpit - as a mosquito cockpit!!
It gets better .... some of the "ground shots" were filmed in a nearby pub (which incidentally I think was also used as a location in "Dad's Army"), so they asked the Puma crew to bring No 2s (battledress in them days) to drink as "extras" in the background! (no pay but free beer!)
Somehow can't imagine MoD approving a task of that nature these days......
