Here's what Trippy members say about Steven F. Udvar-Hazy Center & National Air and Space Museum:
"The National Air and Space Museum is very popular (but the one in Dulles is better - the Steven F Udvar-Hazy Center & National Air and Space Museum) If you make the trek out to Dulles, you can combine it with a short hike and visit to Great Falls National Park." See More
"They'll like the National Air and Space Museum too, but the National Air and Space Museum, Steven F. Udvar-Hazy Center, Smithsonian near the Dulles Airport is better." See More
