I came across a slightly "off the wall" fact about the Brabazon many years ago when I owned a Bristol motor car, a 1957 405 sports saloon (there goes what's left of my incognito!).
Apparently the air intake on the Bristol 404 and 405 cars - which were built in the 1950s at Filton by the aircraft company - was a scaled down version of the Brabazon air intake.
The eminently sensible engineers at Filton semed to have realised that once you've designed a good intake, you can use it elsewhere in the company!
I'll try and dig out a photograh in illustration.....
