Welcome to Litsy!

Previously published as Eyewitness Flying Machine, this is a spectacular and informative guide to the fascinating world of aircraft. Superb color photographs offer a unique "eyewitness" exploration of the history of flight, and provide a close-up view of the many different kinds of aircraft in use today, from helicopters to hot-air balloons. Learn how a jet engine works, why early wings needed "doping", how to keep an airplane flying straight and level, why modern airliners need pressurized cabins, and much, much more.
