X-Plane 9.70 – Cessna 404 Titan. The Cessna Model 404 Titan is an American twin-engined, propeller-driven light aircraft built by Cessna Aircraft. It was that company’s largest twin piston-engined aircraft at the time of its development in the 1970s. The Cessna 404 was a development of the Cessna 402 with an enlarged vertical tail and other changes. The prototype first flew on 26 February 1975. Several interesting liveries are included as these planes were used for a wide variety of tasks. By David Austin.
