Since the first powered human flight in 1903, people have striven to conquer the skies, developing and manufacturing a huge array of aerial war machines. This series focuses on the C-17 plane that revolutionized the U.S Air Force’s transport program; the CH-47 Chinook that has been the Army’s go-to chopper for decades; and drones, that have evolved to fly higher, longer, and more covertly than any manned airplane ever has.
