Packard designed and built a 9-cylinder 980 cubic inch (16,000 cm3) displacement diesel radial aircraft engine, the 225 horsepower (168 kW) DR-980, in 1928. On 28 May 1931, a DR-980 powered Bellanca CH-300, with 481 gallons of fuel, piloted by Walter Edwin Lees and Frederick Brossy set a record for staying aloft for 84 hours and 32 minutes without being refueled.[18] This record stood for 55 years until broken by the Rutan Voyager.[19]
