How It Flies; or, The Conquest of the Air / The Story of Man's Endeavors to Fly and of the Inventions by Which He Has Succeeded

An illustrated technical and historical survey explains the physical properties of the atmosphere and the principles of lift and propulsion, then chronicles the technological progression from early gliders and balloons to powered aeroplanes and dirigibles. Detailed chapters analyze biplane and monoplane forms, alternative designs, engines, and control methods, and offer practical guidance on construction, operation, and model-building. The work concludes with discussions of military applications, concise biographies of prominent aeronauts, a chronological record of achievements, and a glossary of aeronautical terms.
