The BFW M.20 was a German single-engine, high-wing monoplane ten-seat passenger transport aircraft, developed in the late 1920s and early 1930s. Deutsche Luft Hansa used it throughout the 1930s on a variety of routes.

Wilhelm Emil "Willy" Messerschmitt was a German aircraft designer and manufacturer. In 1934, in collaboration with Walter Rethel, he designed the Messerschmitt Bf 109, which became the most important fighter aircraft in the Luftwaffe as Germany rearmed prior to World War II. It remains the second most-produced warplane in history, with some 34,000 built, behind the Soviet Ilyushin Il-2. Another Messerschmitt aircraft, first called "Bf 109R", purpose-built for record setting, but later redesignated Messerschmitt Me 209, broke the absolute world airspeed record and held the world speed record for propeller-driven aircraft until 1969. Messerschmitt's firm also produced the first jet-powered fighter to enter service – the Messerschmitt Me 262.
