Another interesting museum is the Midlands Air Museum at Coventry Airport/Baginton.
At weekend during the summer, many of the aircraft are open. It's not many places where you can sit in the cockpit of a Lighning, Phantom, Starfighter or Vulcan - real Top Gun stuff!
Well worth a couple of hours and reasonable entry too.
A visit could also be combined with an Air Atlantique open day, where you can have a tour around the hangars and a flight in one of their Historic Flight aircraft like the DC3, Twin Pin or Prentice.
