I recently took the opportunity to visit The Vintage Aviator's hangar at Hood Aerodrome, where the aeroplanes are rather hemmed in, but make a pleasant afternoon admiring them at close quarters. In case you're wondering TVAL is one of film director Peter Jackson's wee enterprises and most of the aircraft are very cleverly and accurately reverse engineered from original drawings. A few of these machines are built from original frames, the Camel, Avro 504, the B.E.2f, but most are reproductions, or late productions, as they are pretty much identical to how the aeroplanes were built. If you are into making Great War models, Wingnut Wings is also courtesy of Peter Jackson and TVAL is the one-to-one scale arm!
Fantastic stuff.
As for Chitty Chitty Bang Bang, I've actually pushed that, and sat in it, back in about 1968 or '69, when it was on display in the store where I worked part-time, when I was a student.
That's only a portion of the aeroplanes; the guys there the day I visited said they really need a new hangar. In storage was a Bristol Fighter, another F.E2b, the ex-RAF Museum Hanriot, Pup, S.E.5as, R.E.8 etc...
