ALTUS AIR FORCE BASE, Olka. -- Staff Sgt. Tommy Lock, 97th Logistics Readiness Squadron, refuels a CF-18 Hornet with approximately 1,228 gallons. By hosting the Canadian fighter squadron during their training at Fort Sill, Okla., Altus Air Force Base saved the 25th Tactical Fighter Squadron millions of U.S. dollars and several flying hours allowing the Canadian air force to spend more time training. Previously, the 25th TFS flew out of Fort Worth Naval Air Station Joint Reserve Base, Texas, for their training at Fort Sill. (U.S. Air Force Photo/Senior Airman Amanda Bower)
