The Siebel Si 202 Hummel ("Bumble-bee") was a German light sportsplane of the late 1930s. It was an angular low-wing monoplane, which could be powered by a variety of small engines.

The Volksflugzeug was a grand Nazi-era scheme for the mass-production of a small and simple airplane in the 1930s. It was one of the attempts of the Nazi regime to use consumer technologies as a propaganda tool. Unlike the Volkswagen car, the showpiece of the Nazis’ attempt to appear to work for the good of the average German, as well as the less-known Volksempfänger radio, the Volkskühlschrank refrigerator and the Volksgasmaske gas mask, the Volksflugzeug project was contemplated but never fully realized.
