When you visit DC many who have visited the city before will tell you to go to the Air and Space Museum on the National Mall, especially if you have kids. Well, the original Air and Space Museum on the Mall is not a very dynamic place these days. It really needs a makeover. Instead you need to go out the the Air and Space Museum “annex” out near Dulles Airport. Much more interesting. In addition to tons of planes and space craft (I only show one section of the hanger here) they have an Imax theater and an obvervation tower that overlooks the two runways at Dulles.
