The Smithsonian Institution's National Air and Space Museum houses the world's largest historic air and spacecraft collection, and is a research hub for new scientific technology. Take a look at the Web site's Timeline for a brief history of the museum, and then head over to the exhibitions to read about those past, current and upcoming on display. View the online collections for a more in-depth understanding of topics like the Independent Air Force, Star Wars and the Golden Age of Commercial Air Travel. Browse through the museum's permanent collection database for artifact photos and information. You can also learn in a more hands-on aspect about aviation and space, with online activities like Airplane Anatomy, where you can reconstruct the Wright brothers' first plane, and a geography-from-space quiz. There's even a special Electronic Field Trip section with virtual tours.
