.Egan, Philip S.; Design and Destiny: The Making of the Tucker Automobile; On the Mark Publications; 1989 After purchasing Aircooled Motors, Tucker cancelled all of the company's aircraft contracts so that its resources could be focused on making automotive engines for the Tucker Corporation. This was a significant event, since at the time of Tucker's purchase Aircooled Motors held over 65% of postwar U.S. aviation engine production contracts. For this reason, when the Tucker Car Corporation failed amidst allegations of stock fraud, Aircooled nearly failed with it. Tucker and the Tucker family owned the firm until 1961, when it was sold to Aero Industries, which restored the name Franklin Engine Company. In 1975 the
