The four-engine, pressurized Cessna Model 620 first flew on August 11, 1956 with Ralph Harmon at the controls. This attempt at a business transport was soon dropped in 1957 as it was apparent that there were too many surplus airplanes on the market for this approach to be a financial success. By all accounts, the airplane did fly nicely. The fuselage was sold as scrap and became a house trailer.
