The object of this book is to explain the fundamental principles of aeronautics and to point out the historic development of both the heavier-than-air and the lighter-than-air craft. The treatment is simple. Technical phrases have been avoided wherever possible. Emphasis has been laid on the changes in the design or construction of aeroplanes and dirigibles, which show the evolution of flight and aircraft from early experiments with balloons and gliders to the transatlantic flights of the NC-4, the Vickers “Vimy” Bomber, and the R-34.
