The Salmson 2A2 was one of the most important aircraft of the First World War. It was flown extensively by the French and Americans during the war and by many other countries after the war. This book is the first to cover this classic French reconnaissance and observation plane and is packed with more than 200 photos and many little-known details of its design and combat history. The book also features chapters on all other WWI Salmson aircraft before and after the 2A2. It includes 23 all-new color illustrations showing unit and camouflage markings, as well as all-new five-view drawings to standard modelers' scales of 1/48 and 1/72 covering the S.M.1 and Salmsons 3, 4, and 7, in addition to the 2A2.
