This is a major aviation museum. If you want to know what aircraft they have, you can check the website, which makes you search a database to check the collection. You’ll find that it has many British and American aircraft from WW2 and the post-war period. The American hangar is dominated by a B-52. The museum also has a B-29 Superfortress and a B-17, an Avro Vulcan, etc. Aircraft exhibits fill several hangars. There are also regular flying days. You should plan for an all-day visit.
