Lindbergh's flight across the Atlantic did not directly advance airplane design," MacCready said. "The plane was a lousy plane. It was unstable and you couldn't see forward very well. You wouldn't want to design another like it. But it changed the world by being a catalyst for thinking about aviation." Lindbergh's plane, the Spirit of St. Louis, hangs today from a ceiling at the Smithsonian National Air and Space Museum in Washington, D.C. Hanging next to it is MacCready's Gossamer Condor. The spindly, translucent Gossamer Condor was crafted of aluminum tubing, plastic sheeting, piano wire and Scotch tape. It had a wingspan of 90 feet but weighed only 70 pounds. The pilot was Bryan Allen, a strong, slender bicycle racer who powered the single propeller by pedaling a drive chain made largely of old bicycle parts.

"If you can make something that moves around but gives you the feeling of a prehistoric creature, then people experience it; they feel it much better," MacCready said in a magazine interview.
