Quackenbush's outline of the Wright brothers' work with kites, gliders, and plane is short on both biographical background and technical specifics. He mentions ""the brothers'"" successive development of wing warping and of the elevator, rudder, propeller, and motor, but with only the most cursory explanations of how the devices work. There are no diagrams either; instead Quackenbush indulges in full-page, campy portraits of ""the brothers"" at key moments, and adds a running comic-balloon conversation between a boy and girl at the airport and a pilot who answers their questions. (Behind their backs, two unnoticed birds supply flippant commentary--a typical Quackenbush touch.) A drag.
