Sunday was a work day for CurbCrusher. The show started, but the day ended with an event at the Smithsonian’s Steven F. Udvar-Hazy Center at Dulles. This is the Air & Space Annex that opened a few years ago. There are some nice unique pieces of aviation history here: There is an SR-71 Blackbird, a Concord and the Shuttle Enterprise. However, having had the privilege of visiting the The Astronaut Hall of Fame in Titusville and the Museum of Naval Aviation in Pensacola repeatedly, there is also a bit of a let down at the Smithsonian collection.
