Oh dear,what a badly researched piece of junk this article is.Pictures of the Vulcan? Leuchars and St.Andrews unusuitable? St.Andrews has West Strand Road which would be a good viewpoint/venue,but it`s right beside the golf course.
RAF Leuchars as it used to be held huge Battle Of Britain airshows until the RAF left in 2014,it is now an army base.
Plenty of room for aircraft to land if they wanted to go down that route and have a static display as well.I`m not sure what the status of the runways is at Leuchars,but I think they still have a UAS presence there.
Kirkcaldy does have a nice straight promenade,but that`s about it,it`s probably a little too close to Edinburgh air traffic as well.
