label: Summary
content: The Thomas brothers of Upstate New York began experimenting and flying Curtiss-type aircraft in 1908, and developed their own aircraft in the 1909-10 period. Thomas Brothers aircraft were supplied to the Allied nations during World War I. Airplane engines were built by the Thomas Aeromotor Company, which was later reorganized and became known as the Thomas-Morse Aircraft Corporation of Ithaca, New York. The company's first engine, a 4-cylinder vertical water-cooled design rated at 89.5 kW (120 shp), was produced in 1912. After that, the company confined its efforts entirely to 8-cylinder water-cooled V-types.
