The book, Fighters Of World War I, traces the transition from heavier-than-air spotter aircraft to purpose built fighters during World War I.  With the outbreak of World War I, airplanes were used as a spotter or scouts for opposing armies on the European battlefronts.  In the race for technological superiority, the old-line generals were reluctantly forced to accept these early aircraft as legitimate weapons of war.  While many of the early aviators were chivalrous in the air, some began carrying infantry weapons aloft thus turning their benign airplanes into offensive weapons. As this arms race escalated, purpose built fighters sporting multiple machine guns roamed the skies in search of victims.  Some aviators even turned their fighters into ground attack aircraft by also carrying grenades and eventually small bombs aloft to attack enemy troop positions.  Within four short years, the era of the offensive fighter had arrived and thus began the rapid development of military aviation.  The major sections of this book are as follows: 1) Heavier than Air Craft: State of the Art to 1914; 2) 3 August, 1914: Outbreak of War in the Air; 3) 1914: The Retreat in the Air; 4) 1915-16: The Fighter Comes of Age; 5) Camel Scrap; 6) Bloody April: Slaughter in the Sky; 7) With the Red Baron; 8) The Parachute Story and 9) 1918: The Great Leap Forward.  In addition to an informative narrative, "Fighters Of World War I" includes the following features: 1) Approximately 64 black and white photographs; 2) 5 color photographs; 3) 1 black and white illustration; 4) About 53 color illustrations and 5) 1 map.  This book is 64 pages and is in very good condition.  The editor is Andrew Kershaw with John Batchelor (illustrations).  Edition published in 1976.
