Expanded training at Kirtland Field included a ground school for glider pilots—called the Glider Replacement Center, which was established in July 1942. The center served as a temporary training area for glider pilots awaiting vacancies at glider schools. The Army Air Forces glider-training program had expanded, and prior flight training was eliminated as a necessary qualification for candidates. On 30 June, the War Department opened the program to any man between 18 and 36 who could meet the physical and mental requirements, including civilians as well as officers and enlisted men. At Kirtland Field, the Glider Replacement Center operated until February 1943.
