In this companion volume to 'German and Austrian Aviation of World War 1', Hugh Cowin unearths some real gems from his photographic collection, and at the same time he details every aircraft type that saw action in WWI. As a reference title it is second to none; as a remarkable story of courage and technical innovation it makes a riveting narrative. British fighter ace Captain Albert Ball and the US's pilot/designer Chance M. Vought stand alongside lesser-known but equally fascinating characters such as the Russian Navy aviator Major Alexander de Seversky. By turns anecdotal and authoritative, Cowin provides a truly comprehensive account of the Allied aviation of World War 1.
