Col. Thurman H. Bane makes the first flight of the Army Air Service’s first rotorcraft at McCook Field, Ohio. Bane reaches an altitude of six feet, covers nearly 300 feet, and hovers for one minute and 42 seconds. The 65-foot diameter X-shaped vehicle, developed by George de Bothezat, a Russian immigrant working for the Army, utilizes four six-bladed rotors for lift. Several subsequent tests were all successful, but the Army loses interest in the project.
