Junkers A50 Junior

The Junkers A50 Junior is an all-metal sports plane designed and produced by the German aircraft manufacturer Junkers.

Designed by Hermann Pohlmann during the late 1920s, it incorporated the all-metal construction and various other principles practiced on Junkers' larger aircraft of the era. The A50 had a streamlined fuselage composed of corrugated duralumin, a low-mounted cantilever wing, and proportionally large flight control surfaces. It could be outfitted with conventional landing gear, skis or floats to suit a variety of different operational conditions; the aircraft was reportedly suitable for use in the tropics or near-arctic conditions as well as from austere airstrips. It was typically powered by a single Armstrong Siddeley Genet II engine, although other powerplants could also be fitted.

On 13 February 1929, the A50 conducted its maiden flight. During the following year, a series of eight FAI world records for altitude, range, and average speed were set on a floatplane variant of A50. During 1931, Marga von Etzdorf flew an A50 solo from Berlin to Tokyo, the first woman to do so.
