An investigation into how machines and living creatures fly, and of the similarities between butterflies and Boeings, paper airplanes and plovers.
Tennekes (earth sciences, Free U. of Amsterdam) explains to lay readers the aerodynamic principles that underlie the flight of everything, including paper airplanes, kites, gliders, and human- powered aircraft. He also explains such concepts as lift, drag, wing loading, and cruising speed; and the impact of fuel efficiency, headwind, tailwind, and other factors.
