Lyman Wiswell Gilmore, Jr. (June 11, 1874 - February 18, 1951) was an aviation pioneer. In Grass Valley, California, he built a steam-powered airplane and claimed that he flew it on May 15, 1902. Due to the requirement of a heavy boiler and the dependency on coal as a power source, the flights would have been unsustainable. Records and evidence relating to his claim were lost in a 1935 hangar fire. == First flight == Gilmore, in a 1936 interview, reported a successful tethered glider flight in 1893 and a free glider flight in 1894.〔 Gilmore further added that (although he had not reported it until 1927) he made a controlled steam-powered flight on May 15, 1902,〔 however all records and papers related to his aircraft were destroyed in a fire. There are photographs from 1898 showing Gilmore's machine, but none showing it in the air. The claims of the aircraft achieving flight are unconfirmed, and given the weight evident by the grounded aircraft photos, the possibility of flight is highly unlikely.
