Flugschule
With the sudden end of World War I in November 1918, the future operational status of Mather Field was unknown. Many local officials speculated that the U.S. government would keep the field open because of the outstanding combat record established by Mather-trained pilots in Europe. Locals also pointed to the optimal weather conditions in the Sacramento area for flight training. Cadets in flight training on 11 November 1918 were allowed to complete their training, however no new cadets were assigned to the base. The separate training squadrons were consolidated into a single Flying School detachment, because many of the personnel at Mather were being demobilized. Flight training activities finally ceased on 8 November 1919.
