Thanks Kevin for your mention.
I would however challenge any engineer to devize a car design that would be
able to suck exhaust fumes back into the vehicle from behind the rear
bumper!
As an anecdote I was recently in the Science Museum in London with my son
(and was actually able to park in my old spot next door when a student at
Imperial!).
In the museum were of course fantastic steam engines and aeroplanes,
including the Rover JET 1, but when I saw as an addition what they claimed
to be a capsule that had actually landed on and returned from the moon, I
thought, no, that couldn't be possible in the 1970's.
I mean, consider the faulty door seals, and leaky exhausts!
Where were Bristol then?
With best regards,
Andrew Knox.
