3,4 hours depends how much you like history and army
You can skip though, including the guided parts, in about 90 minutes. If you take the time to listen to all of the displays and demonstrations, expect to spend many hours.
Hi, Maybe two or three hours.
It took us a couple of hours to enjoy the whole thing. If you are deeper into the history, planes, etc, you could spend a lot more time. We loved it.
