Never thought about a steam powered plane. They did back in 1933.
1933: George D. Besler and William J. Besler's prototype steam biplane, based on a Travel Air 2000, flew several times at Oakland airport. It was powered by a two-cylinder, 150 hp (110 kW) double-expansion V-twin reciprocating engine weighing about 500 lb (230 kg), designed by the Doble Steam Motors Company and Besler.[7][8] and was capable of STOL operation due to the ease of reversing the thrust.[9][10]
