Explorer Hiram Bingham discovered Machu Picchu in 1911, as recounted in his book Inca Lands, now released on Librivox at http://librivox.org/inca-lands-by-hiram-bingham/. In 1917, he became an aviator and organized the United States Schools of Military Aeronautics at eight universities to provide ground school training for aviation cadets, and then in Issoudun, France, Bingham commanded the primary Air Service flying school. He became a supporter of the Air Service in their post-war quest for independence from the Army and supported that effort, in part, with the publication of this book of his wartime experiences published in 1920 by Yale University Press.
