Amid the continuous struggle for aerial superiority during World War I, two aircraft types were at the forefront. Both rotary engined fighters, the Sopwith Camel and the Fokker Dr I triplane were relatively slow for their time, but were regarded as the most manoeuvrable machines produced during the conflict, and the classic pair for a tight, evenly matched dogfight at close quarters. In this book Jon Guttman examines the fascinating story of the design and development of these deadly foes. First-hand accounts and innovative cockpit-view artwork give a thrilling insight into the pilots' experiences during the world's first aerial duels and helps explain their successes and failures.
