"The evolution of American science itself, from empiricism to a more German, theoretical approach to problem solution, is only indirectly addressed through the evolution of airpower. The biographical approach, emphasizing scientific and technological elements in Arnold’s and Kármán’s lives, is essential because the interaction of personalities, as well as their institutions, is inexorably linked to the development of American airpower. The importance of the personalities involved precludes a purely technological history of the airplane or the Air Force as a system within itself. For in the end, it was two men using their broad experience and innovative ideas, who created the blueprint with which American air supremacy has been built."
