Who created the engines used in the aircraft of the aviator who completed the first solo transatlantic flight?
Frederick Rentschler Frederick Brant Rentschler (November 8, 1887 – April 25, 1956) was an American aircraft engine designer, aviation engineer, industrialist, and the founder of Pratt & Whitney Aircraft. Rentschler created and manufactured many revolutionary aircraft engines, including those used in the aircraft of Charles Lindbergh, Amelia Earhart and James Doolittle. He is also a co-founder of United Aircraft and Transport Corporation, the predecessor of United Technologies Corporation.
Biplane A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s.
