    • The National Air and Space Museum holds in trust over 60,000 artifacts and more than 20,000 cubic feet of archival materials. Historic aircraft and space artifacts, such as the 1903 Wright Flyer and the Apollo 11 Command Module Columbia, highlight the National Collection.

    Thousands of additional artifacts—including engines, rockets, uniforms, spacesuits, balloons, artwork, documents, manuscripts, and photographs—document the richness of the history of flight. A wide variety of these artifacts are on display at the Museum in Washington, DC and the Steven F. Udvar-Hazy Center in Chantilly, VA.
