NACA to NASA to Now: The Frontiers of Air and Space in the American Century tells the story of the National Advisory Committee for Aeronautics (NACA) and its successor, the National Aeronautics and Space Administration (NASA). The NACA and NASA facilitated the advance of technology for flight in air and space throughout the 20th and into the 21st century. This book explores how and why aerospace technology took the course it did, discusses some of the key people who drove aerospace science and technology development, and examines the political, economic, managerial, international, and cultural contexts in which the events of flight have unfolded.
