I went to the Cosford Air Show once. It was a wonderful day, but I wasn't at the actual airfield itself. I was on a green at the other side of the airfield, in Albrighton, on a housing estate where they had their own stalls, burger vans, and even a knowledgable commentator. The highlight of the day was seeing a Vulcan Bomber come directly overhead. I've never seen anything so huge fly so slowly, and at such a volume. Awesome sight.
