Perhaps no technological development in the century has more fundamentally transformed human life than the airplane and its support apparatus. The nature of flight, and the activities that it has engendered throughout the world, makes the development of aviation technology an important area of investigation. Why did aeronautical technology take the shape it did? Which individuals and organizations were involved in driving it? What factors influenced particular choices of technologies to be used? More importantly, how has innovation affected this technology? Innovation and the Development of Flight, a first strike at the "new aviation history," represents a significant transformation of the field by relating the subject to larger issues of society, politics, and culture, taking a more sophisticated view of the technology that few historians have previously attempted. This volume moves beyond a focus on the artifact to emphasize the broader role of the airplane and, more importantly, the entire technological system. This suggests that many unanswered questions are present in the development of modern aviation and that inquisitive historians seek to know the relationships of technological systems to the human mind. Some of the subjects discussed are early aeronautical innovation and government patronage; the evolution of relationships among airports, cities, and industry; the relationship of engine development to the entire aviation industry; the Department of Commerce's influence on light plane development; pressure in the Air Force for the development of jet engines; and lessons of the National Aerospace Plane Program. Aviation historians and historians of technology will find Innovation and the Development of Flight a valuable examination of aeronautical innovation providing foundations for continued explorations of this field.

Allied Aircraft Piston Engines of World War II, now in its second edition, coalesces multiple aspects of war-driven aviation and its amazing technical accomplishments, leading to the allied victory during the second world war. Not by chance, the air battles that took place then defined much of the outcome of one of the bloodiest conflicts in modern history. Forward-thinking airplane design had to be developed quickly as the war raged on, and the engines that propelled them were indeed the focus of intense cutting-edge engineering efforts. Flying higher, faster, and taking the enemy down before they even noticed your presence became a matter of life or death for the allied forces. Allied Aircraft Piston Engines of World War II, Second Edition, addresses British- and American-developed engines. It looks at the piston engines in detail as they supported amazing wins both in the heat of the air battles, and on the ground supplying and giving cover to the troops. This new edition, fully revised by the original author, Graham White, offers new images and information, in addition to expanded specifications on the Rolls-Royce/ Packard Merlin and the Pratt & Whitney R-2800 engines. Jay Leno, a known enthusiast, wrote the Foreword.

The American military establishment is intimately tied to its technology, although the nature of those ties has varied enormously from service to service. The air force evokes images of pilots operating hightech weapons systems, striking precisely from out of the blue to lay waste to enemy installations. The fundamental icon for the Marine Corps is a wave of riflemen hitting the beaches from rugged landing craft and slogging their way ashore under enemy fire. How did these very different relationships with technology develop? During the interwar years, from 1920 to 1940, leaders from the Army Air Corps and the Marine Corps recreated their agencies based on visions of new military technologies. In War Machines, Timothy Moy examines these recreations and explores how factors such as bureaucratic pressure, institutional culture, and America's technological enthusiasm shaped these leaders' choices. The very existence of the Army Air Corps was based on a new technology, the airplane. As the Air Corps was forced to compete for money and other resources during the years after World War I, Air Corps leaders carved out a military niche based on hightech precision bombing. The Marine Corps focused on amphibious, firstwave assault using sturdy, graceless, and easytoproduce landing craft. Moy's astute analysis makes it clear that studying the processes that shaped the Army Air Corps and Marine Corps is fundamental to our understanding of technology and the military at the beginning of the twentyfirst century.

Author Francis Bradford, a former Hall-Scott engineer, provides valuable resources and insight not available to any other Hall-Scott researcher. Well-illustrated with numerous photos, drawings, and memos, this fascinating book will be of interest to history buffs in the areas of aviation, rail, marine, trucks, buses, fire equipment, and industrial engines, and to World War and military historians.
