Learjet 35/36

The Learjet 35 and Learjet 36 are a family of American business jets and military transport aircraft built by Learjet from 1973, and the Model 35 went on to sell more than any other Learjet. Both are powered by two Garrett TFE731 turbofan engines mounted on the sides of the rear fuselage, with fuel tanks on the wingtips and a cabin for six to eight passengers; the Model 36 has a shorter cabin to make room for more fuel and about 500 miles more range. The design grew out of a Learjet 25 fitted with a TFE731 turbofan that first flew in May 1971. The first Model 35 prototype flew on 22 August 1973 and the type was certified in July 1974, and the upgraded 35A and 36A followed in 1976. The United States Air Force bought the 35A as the C-21A. Production continued after Bombardier bought Learjet in 1990 and ended in the 1990s.
