Alexandre Goupil's Sesquiplane
Alexandre Goupil was a French engineer, best known for designing and testing a flying machine in 1883. The machine was a sesquiplane, which is a plane with two sets of wings, one much smaller than the other. It was to be powered by a steam engine housed in a bulbous, streamlined body, which powered a single propeller at the front of the craft. The machine had a wingspan of 6 meters (20 feet), and had space for an operator to stand below the body.
