In 1946, when Freeman Field was scheduled to close, Air Technical Service Command had to move the aircraft. The larger aircraft were sent to Davis-Monthan Field, Arizona, and the fighter aircraft sent to the Special Depot in Park Ridge, Illinois (now O'Hare Airport), which was under the control of ATSC's Office of Intelligence. The Special Depot occupied buildings that Douglas Airplane Co. had used to build C-54 aircraft. The aircraft were stored in these two locations until they could be disposed of in accordance with General Arnold's order.
