The first Army Aviation School began operations at the airfield in 1911 with five new aeroplanes, including two Wrights, two Curtiss, and one Burgess-Wright, and four hangars adjacent to the road, while several civilian hangars had to be relocated to align with the Army hangars. Its instructors included Captain Charles deForest Chandler, Captain Paul Beck, and Lieutenants Henry "Hap" Arnold, Thomas Milling, Roy Kirkland, Leighton Hazelhurst, and Lewis Rockwell. In 1911 and 1912, important aviation achievements there included an Army altitude record by Hap Arnold at 6,540 feet, the development and testing of a bomb sight by Riley Scott, early aerial photography testing from a military plane, the first machine gun fired from a plane, and the first enlisted man to die in an aviation accident, Corporal Frank Scott.
