This authoritative guide to the history and science of flight answers all the questions that kids will ask (and that parents may not be able to answer), like "What makes a plane stay in the air?" "What's a sonic boom?" and "How do astronauts go to the bathroom in space?"

Contains 12 fact cards on the coolest aircraft, a large double-sided poster, and 9 paper airplanes in three designs (a historic glider, a military jet, and a space shuttle) with easy-to-follow folding instructions.
