The Grumman Cheetah

With Dr. Bill Harrison. In 1972 it began as the American Traveler, then Grumman bought the company and tried to get a little more speed out of it. Tweaks to the airframe gained seven knots with the same 150 horsepower and so it deserved the Cheetah name it got in 1975 with the leaping Cheetah emblem. Gulfstream bought it later and continued production to 1979, with a total of 900 Cheetahs built. The aircraft was a success thanks to bonded wings and a honeycomb fuselage that got rid of rivets and added speed. Length 2:38.
