29 September 1842 inventor William Henson has published a draft of an airplane with a steam engine. A patent application for this invention, he registered back in March of the same year. Unfortunately, information on the construction of the first in aviation history model airplane remained very small. The project was called "Aerial steam carriage" and according to plan, the aircraft was one wing with the area of 3.7 sq. m., covered with silk. As an energy source is made by a single-cylinder machine, the weight of which together with the boiler, fuel and water accounted for only 2.7 kg. unfortunately, the successful flight of this design was not the model was immediately dropped after leaving the launch ramp. To 1845 Henson with the mechanic Stringfellow was able to build a new glider with a wingspan of 6.1 m high and weighs about 12 kg. But the first successfully flew the model did all the same, John Stringfellow, but already in 1848. And only 50 years later another scientist, Clement Ader, was built the plane, which took off without overclocking the ramp. Before the invention of airplanes with steam engines, scientists tried to harness the power of the muscles, but quickly abandoned the idea. Many of the major scientists even denied the possibility of creating an aircraft heavier than air.
