Phileas, I get the distinct impression you actually want the airport to be shut down just so you can say I told you so.
Deano,
In two of my previous lives I've worked on both sides of the runway at St. Mawgan, circa 1977 I was there in a blue uniform for an exercise "Ocean Safari" and in the 80's I found myself working for Brymon ... So I do have a soft spot for the old place.
Now as for your naive and wrongful assumption that I want the place shut down, sitting here on a tropical beach where I have semi-retired to (check out "Siargao Island" on Goggle Images) I couldn't give a flying fook whether St. Mawgan stays or goes, I'm merely being truthful that the commercial viability of it as a sole civilian airport is a joke and it will NEVER return a single penny of profit.
Saying that I guess the same could have been said for Wideawake Airfield, that it would never return a penny in profit, but that changed during 1982 ... Perhaps St. Mawgan needs a war also to turn a profit
