On one of my recent trips to Washington DC, I finally visited the new annex to the Smithsonian Air & Space Museum, the
Steven F. Udvar-Hazy Center near Dulles International Airport. They've got a nice collection, which will grow as other items are restored from the Smithsonian's vast collection. Of particular note are the
Enola Gay (picured above), the Shuttle trainer
Enterprise, and an SR-71 Blackbird. Definitely worth the trip.
