William F. Milliken's handling research is fundamental to modern automobile design, and his definitive books on vehicle dynamics provide engineers and racers with practical understanding of chassis design for maximum performance. Equations of Motion is the story of Milliken's lifetime of experimentation and innovation in vehicle stability and control. In 1933, at age 22, Milliken built and flew his own wood-and-fabric airplane from Old Orchard Beach, Maine. During the war he helped resolve the Vought F4U Corsair fighter's aerodynamics, and risked his own neck as a test-pilot to push the Boeing B-17 bomber's operating ceiling above the flak and to make the experimental B-29 flyable. While at CAL, Milliken joined the infant Sports Car Club of America (SCCA), driving a variety of Bugatti, Miller, and other race cars at the first Watkins Glen, Sebring, and Bridgehampton races, as well as in the Pikes Peak, Mt. Equinox, Giant's Despair and other hillclimbs. Ever the engineer, he analyzed each performance in light of his aeronautical progress, laying the foundation for modern automotive chassis design. In Equations of Motion: Adventure, Risk and Innovation, Milliken vividly recounts his experiences pushing airplanes and race cars beyond their limits. His exciting life provides singular, real-world insight into the challenge and joy of engineering and the history of vehicle dynamics as he created it in the air and one the track.
