Pacific Western Airlines does some outdoor maintenance for the Air Force. Canada placed an order for four Lockheed C-141s for conversion to air refueling tanker. Lockheed had already closed the production line and would not re-open it for only four aircraft. A cancelled order for Western Airlines 707s was taken over instead and the 707s served 1970 - 1995. 13701 was declared surplus in 1993 and worked as a freighter 1994 - 2000. Last registered to Mexicargo (XA-ABG) it was stored at Marana, AZ in 2000 / 01 and scrapped by 2005.
