After going through the main museum, plan on visiting the special

These are in a building on the Base (C street?). The museum will
give you a car pass. I don't think you can visit without a car.

That all changed after 9/11. Now they have a shuttle bus, which you need
to get a reservation to ride. You also need to have a photo ID or passport
to show them before you will be allowed on the bus:
