American Jets Roar Over Arctic -- Three U.S. Air Force Northrop Scorpion F89D all-weather interceptors fly in close formation over the frozen Arctic. Assigned to the 64th Fighter-Interceptor squadron at Elmendorf Air force Base, Anchorage, Alaska, these 600 mile an hour jets are part of the U.S. aerial defense fleet guarding the vital approaches to the United States against air attack. The planes are America's most heavily armed fighters. November 10, 1954. (Photo by AP Wirephoto).;American Jets
