Written in 1911 by a professor of mechanical engineering at the Polytechnic Institute of Brooklyn, this illustrated survey explains aviation in its first heroic years. Ennis covers the delights and dangers of flying, soaring flight, how a machine turns corners, stability, propellers and the engines that kept the earliest aeroplanes aloft.
A vivid snapshot of aeronautics less than a decade after the Wright brothers, for history-of-flight enthusiasts. Download the free EPUB.
