From the manufacturer:
The Lockheed C-140A Jet Star is an American administrative plane, first flown in 1957. Series production lasted from 1961 to 1979, during which time 204 machines were built. Its principal task was the transportation of VIPs. Apart from the U.S. Air Force, it was used by the Air Forces of Canada and Germany, and was exported to Mexico, Saudi Arabia, Kuwait, Iran and Iraq. Several private planes of this type continue to be used today.
