The Schneider Trophy was a focus not just of remarkable aircraft, derring-do pilots and swooning public attention, but also of fierce rivalries between the competitors: Britain, France, Italy and the United States. It gripped the imaginations of pioneering manufacturers and two of the world’s finest aircraft designers - Reginald Mitchell and Mario Castoldi – who worked feverishly hard to outdo one another. Perhaps inevitably, the dynamism of rival engineering and politics led to the most potent military fighters of World War Two with Reginald Mitchell’s record-breaking Supermarine seaplanes morphing, one way or another, into the Spitfire. This book not only tells the story of the Schneider Trophy afresh but also examines the backdrop and legacy of these legendary air races, which became a driver and celebration of speed and engineering prowess for both sea and ground-based aircraft. It is an exhilarating tale of raw adventure, public excitement, engineering genius and the fortunes of flying boats and seaplanes. Illustrated with colour and b&w photographs.
