They just do it differently. Why Don't Jumbo Jets Flap Their Wings? offers a fascinating explanation of how nature and human engineers each arrived at powered flight. What emerges is a highly readable account of two very different approaches to solving the same fundamental problems of moving through the air, including lift, thrust, turning, and landing. The book traces the slow and deliberate evolutionary process of animal flightA¹in birds, bats, and insectsA¹over millions of years and compares it to the directed efforts of human beings to create the aircraft over the course of a single centuryaequal and opposite reaction, a pushing the engine (and its attached airplane) forward. Although engineers have come up with several different kinds of jet engines, all the practical ones used on airplanes are turbojets or turbofans. A turbojetanbsp;...
