Excerpt from Langley Memoir on Mechanical Flight: Part I. 1887 to 1896; Part II. 1897 to 1903 Persons who care only for the accomplished fact may be inclined to under rate the interest and value of this record. But even they may be reminded that but for such patient and unremitting devotion as is here enregistered, the now accomplished fact of mechanical ight would still remain the wild unrealized dream which it was for so many centuries.

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.

In keeping with its bestselling previous editions, Fundamentals of Aerodynamics, Fifth Edition by John Anderson, offers the most readable, interesting, and up-to-date overview of aerodynamics to be found in any text. The classic organization of the text has been preserved, as is its successful pedagogical features: chapter roadmaps, preview boxes, design boxes and summary section. Although fundamentals do not usually change over time, applications do and so various detailed content is modernized, and existing figures are replaced with modern data and illustrations. Historical topics, carefully developed examples, numerous illustrations, and a wide selection of chapter problems are found throughout the text to motivate and challenge students of aerodynamics.
