In 1917, he was promoted to major. The Marine Corps also approved a request for Turner to be temporarily assigned to the Army Signal Corps. While assigned to the Signal Corps, he held command of Ellington Field, an Army Air Station in Houston, Texas. On March 14, 1918, Turner earned his wings and was designated as Naval Aviator #772. He was also designated as the 73rd Marine aviator. In October 1919, Turner was given orders to take part in combat operations against bandits with the First Provisional Marine Regiment in Haiti. When he left Haiti in 1920, Lieutenant Colonel Turner was the senior ranking Marine aviator. Turner's friend, CommandantJohn A. Lejeune, appointed him as the Officer in Charge, Aviation for the Marine Corps in December 1920. He would fill this position until March 1925. On April 22, 1921, Turner set a record for the longest flight ever made by a Marine or Naval aviator when he led two Airco DH-4s on a flight from Washington, D.C. to Santo Domingo and back. For this flight, Turner was awarded the Distinguished Flying Cross. Turner later went to China to command the Marine aviation elements of the 3rd Brigade. Supporting the peace-keeping operations in China, the Marine squadrons flew nearly 4,000 sorties. These sorties included conducting photographic reconnaissance of Chinese forces and transporting mail and passengers. Brigadier General Smedley Butler praised Turner and his aviators for their service in China. In May 1929, Turner, now a colonel, was again made the Officer in Charge, Aviation.
Death
On October 22, 1931, Colonel Turner flew a new amphibiousboat plane, the Sikorsky RS-1, to the Marine headquarters in Haiti. On October 26, he made a normal landing at a beach in Gonaïves, Haiti. The port landing gear sank into the sand about two feet, and Turner exited the plane to inspect the damage. Turner did not take the list of the plane into account when he walked by the propellor, and he was struck in the side of the head and critically injured. He died two days later on October 28 in a field hospital in Port-au-Prince. At the time, Turner was one of the best known aviators in the Marine Corps. Turner was also due to be promoted to brigadier general, which would have made him the first Marine aviator to hold that rank. Turner’s body was returned to the United States and he was laid to rest in Arlington National Cemetery on November 5, 1931. Major Roy Geiger replaced Turner as the Officer in Charge, Aviation on November 6. The position was left unfilled for nine days due to the untimely death of Colonel Turner. Turner Field at Marine Corps Air Facility Quantico was named in his honor. The 1st Marine Aircraft Wing was later formed on Turner Field in July 1941.
