Apollo 11 crew at the National Air and Space Museum

Neil Armstrong

A public appearance by Neil Armstrong is rarer than a sighting of a megamouth shark, but he joined his Apollo 11 crewmates last night for the annual John Glenn lecture at the Smithsonian’s National Air and Space Museum, commemorating the 40th anniversary of the first moon landing. The Times has coverage of the event; NASA has video of the entire evening on YouTube and a photoset on Flickr.
