This was by far one of the best aviation museums we have visited!! Our family (5 people) found it amazing, we could have been there all day. I really liked the layout- the free flowing groups of planes and the openness of the space. Space shuttle Discovery was by far the best part. Our children ages from 4-13 were amazed with the whole museum. This one is a winner!
Highly recommended. Go at 4pm when parking is free, it will give you enough time to see everything, and it will cost you nothing. We loved it. This Air and Space museum was much better than the other one in Washington DC.
