Space Shuttle Discovery salutes Washington on historic final flight

As historic flights go, this has to be right up there with the best of 'em. Space Shuttle Discovery performed a final fly-by over the capital, and created a trail of excited spotters as it did so. Perched atop a Boeing 747, the iconic craft was flying at a relatively low 1,500 feet according to NASA. Pictures of the voyage have been popping up on social media and image sharing sites as it headed in from the west, before coming to its final resting place at a special off-shoot of the Smithsonian Institute's National Air and Space Museum near Dulles Airport.
