The space shuttle Discovery (OV-103) was transferred this morning from NASA to the Smithsonian's National Air and Space Museum (NASM) at Dulles Airport. But not before buzzing over DC, atop a modified 747 that has transported shuttles from coast to coast. Quite a regal sendoff, and the crowds on the Mall were electrified!
