Very nice pics! I have seen these in person and have a very similar set of photos!
These are all taken at the National Air And Space Museum Steven F. Udvar-Hazy Center at Washington Dulles Airport (KIAD), near Washington D.C.
There is an observational tower that overlooks the field at KIAD. Live air traffic control audio plays over speakers in the tower.
There is also a very nice space exploration exhibit, whit the Space Shuttle Enterprise as it's center piece.
I encourage every aviation enthusiast and buff to visit the Udvar-Hazy Center. It's a great place to visit!
