This could be a massive task. In theory, the likes of Feltwell, Molesworth, Upwood and Menwith Hill are RAF stations, (USAFE), but you're unlikely to get much of a reception there. And none at all at Bentwaters or Upper Heyford.
Same could be said of the likes of Little Rissington, Mona, even Keevil. Still an RAF airfield, but no peeps.
Then there's the places where there are RAF staff (lots of them, in some cases), but not an RAF site.
