Hello, The C-141, C-130, and C-5 are open to the public. The C-47 is available to tour with a guide. The museum does not have a C-17 (I'm sure many confuse the C-17 for the C-5) nor is one available for touring. The museum is currently open Wednesday through Sunday, 9am to 4pm.
The tour guides have the ability to open upon request the C17, C5, C47. Weather dependent. Open every day but Monday..9:00-4:00.
My understanding is there are very few open during the week, but on weekends and some special days more are open. If you get with one of the tour guides you can sometimes get a tour of the C17 and that is extremely interesting.
