Wings Over the Mexican Border by Kenneth Ragsdale, a Texas historian, is about the rise of U.S. military aviation in the rugged borderlands of Texas during the 1920s, 1930s, and 1940s. The book describes the development of U.S. air power at a remote airfield on a Big Bend ranch, which served as a proving ground for reconnaissance and emergency response capabilities, set against a backdrop of border banditry, revolution, and World War II.
