The book, Air Force: A Pictorial History Of American Airpower represents a comprehensive chronicling of the evolution of air power under first the United States Army Air Corps and later the United States Air Force.  The publication of "Air Force: A Pictorial History Of American Airpower" occurred on the 50th anniversary of this military organization and was only possible through the close cooperation between the author and the United States Air Force.  Most of the photographs are action pictures, whether of men or machines.  The presentation of the captions, text and photographs serve to chronicle the step-by-step progress of America's rise to become the world's premier airpower.  While it is clear that the United States Air Force and its predecessor organizations forecast the most accurate use of airpower when called upon for battle, the faulty judgments and errors made along the way are covered as well.  The information presented in "Air Force: A Pictorial History Of American Airpower" is accurate and highlights memorable accounts of the first gun fired from an aircraft, early strafing experiments, distance records, speed tests and details about various types of airplanes, individuals and battles.  The major sections of "Air Force: A Pictorial History Of American Airpower" are as follows: 1) The Beginning; 2) War In The Air; 3) The Golden Age Of Aviation; 4) Airpower Comes Of Age - Tests Replace Theory; 5) Airpower You Can Touch; 6) War Finds AAF Unprepared; 7) AAF Takes Offensive; 8) Another World, Another Air War; 9) AAF Becomes Supreme Power; 10) Japanese Hammered By Day And Night; 11) The Pay-Off; 12) No Shortage Of Responsibility; 13) Korea - At The Edge Of WW III and 14) Airpower Today.  In addition to an informative narrative, "Air Force: A Pictorial History Of American Airpower" includes approximately 394 black and white vintage photographs.  This book is 232 pages and is in good condition with only minor tears and wear evident on the dust cover.  The author is Martin Caidin.  Edition published in 1957.
