Very Interesting, do you have any more data on
this, besides the dimensions quoted in the PDF?
Portsmouth Aviation are still going,
I see they make the UK version of the Paveway LGB....
Regarding the Aerocar, my first thought whenever I see it
is 'Miles Aerovan', although the latter is somewhat larger,
and, of course, designed as a freighter.
Of course, DH weren't going to let go of the Rapide replacement
market, the DH Dove appearing in due course...
