As an ex-fishead I would point out that one of the best is the Army Air Corps museum at Middle Wallop. I'm sure you'd be able to fly in there.
And whatever you do, don't miss Shuttleworth's saturday evening flying displays, they are awesome if only for the rarity of what flies there. A formation of Spit, Hurricane, Gladiator and Lysander on my last visit, the L shaped crowd line is both a display pilot's and photographer's dream. Take a picnic too.
Have fun!
And how did we forget the RAF museum at Hendon, no flying there since the thirties but what a collection, even if you do have to drive.
