What air craft ended production in 1992 and was derived from the same aircraft as the Boeing C-137 Stratoliner?
Boeing C-137 Stratoliner The Boeing C-137 Stratoliner was a VIP transport aircraft derived from the Boeing 707 jet airliner used by the United States Air Force. Other nations also bought both new and used 707s for military service, primarily as VIP or tanker transports. In addition, the 707 served as the basis for several specialized versions, such as the E-3 Sentry AWACS aircraft. The designation C-18 covers several later variants based on the 707-320B/C series.
Ilyushin Il-2 The Ilyushin Il-2 (Cyrillic: Илью́шин Ил-2) Sturmovik was a ground-attack aircraft (Cyrillic: Штурмови́к, "Šturmovík") produced by the Soviet Union in large numbers during the Second World War. With 36,183 units of the Il-2 produced during the war, and in combination with its successor, the Ilyushin Il-10, a total of 42,330 were built, making it the single most produced military aircraft design in aviation history, as well as one of the most produced piloted aircraft in history along with the American postwar civilian Cessna 172 and the Soviet Union's own then-contemporary Polikarpov Po-2 "Kukuruznik" multipurpose biplane.
