This fully illustrated guide to the world's most-visited aviation and space museum is both an indispensable companion for visitors and a detailed history in itself of humanity's quest for flight. The Smithsonian Institution's National Air and Space Museum maintains the world's largest collection of historic aircraft and spacecraft plus an amazing assortment of other historic objects. Many fascinating items from the twenty-three galleries and two off-site facilities--including the Wright Flyer, Chuck Yeager's Bell X-1, and the spacesuits worn by Neil Armstrong and Buzz Aldrin--are presented here in 200 full-color photographs, accompanied by their equally intriguing stories.
