Hehe. A real classic. I can't speak for Fozzer but I wasn't in the film.
The full title is "Those Magnificent Men in Their Flying Machines, or How I Flew from London to Paris in 25 hours 11 minutes.". It's loosely based on the air races held before WWI. The book is actually better than the film. IMHO
The sewage farm on the airfield boundary plays a big part in the proceedings & the antics of the German contingent reduced me to hysterics.

My father-in-law & brother-in-law both worked for Miles Aviation & were involved with building some of the replica aircraft used in the film. The Bristol Boxkite was one of theirs.
http://www.filton.flyer.co.uk/bristol/survboxgaspp.htmSome of these aircraft are still flying today in various parts of the world. I believe the Shuttleworth Trust has some, their Antoinette being another example. I'll have a punt round later to see if I can find a full list. I'm not sure there will be too many examples for FS.
PS. I think it was mostly filmed in England but I'm not sure of the location. The airfield & starting point for the race was based on the famous vintage aerodome at Brooklands. I believe the beach shots were done at Brighton.
