The Air Museum at Dulles airport is a must see. The Enola Gay is there, a Concorde, a space shuttle and hundreds more all under one roof. Absolutely fascinating, especially for the young ones. Been there 3 times, want to go again.

Yes, I live in the DC area and have seen and done everything. My favorite spot in the whole area is the Air and Space Museum at Dulles. Absolutely fascinating. It is a must.

I agree.
Unfortunately, Dulles is a l-o-o-o-n-g ways from the DC mall.

Even today, after so many visits, I would not want to visit DC for less than a week.
