Thank you for that cj. I knew that Weston Airport was very busy at one point in the 1930s, not least with the ferry flights to Cardiff, but I hadn't realised it was that busy.
I went to school at Weston in the 1950s and always meant to go up on the 7s 6d (37.5p) pleasure flights from there then but I never did.
So, a Severnside airport (well, almost) might have appeared several decades before the various schemes that have been put forward for such a facility over the past quarter of a century. The land on either side to the east and west is pretty flat so a long runway should not have been a problem. It would certainly have been a better site than Lulsgate but if Filton had been available that was the obvious choice in my view.
Weston Airport, like parts of Filton airfield, now seems to be the scene of a huge new housing development, although I believe that the large helicopter museum on the site is still going strong.
