A history of sustained flight concentrates on the development of ideas, designs and inventions from the earliest thoughts, legends, myths and prophecies to the successful use of aircraft in World War I and adds a postscript on the possibilities of the future in view of gas turbines, rockets, electronics and atomic fission and their contribution to aeronautics. These are the contributory accomplishments -- and many failures -- which led to the unifying of a dominant dream. The story ranges from the first use of aerodynamic principles in the arrow, the boomerang and the kite down the years to balloons, gliders, parachutes, airships and powered aircraft. It is a conscientious record that tallies fantasies with adventure -- and tragedy; that contrasts pioneering research with later application as the legacies reached their inheritors, sometimes centuries after. There's a definite personal enthusiasm here for aviation and an excellent collection of illustrations and drawings that make this a good background look for a market that may, at the half century mark of power flight, not be as uncritical as the earlier one.
