The Messerschmitt Bf 108 Taifun is a German single-engine sports and touring aircraft developed by Bayerische Flugzeugwerke (Bavarian Aircraft Works) in the 1930’s. The Bf 108 is of all-metal construction.

Originally designated the M 37, the aircraft was designed as a four-seat sports/recreation aircraft for competition in the 4th Challenge de Tourisme Internationale (1934). The M 37 prototype flew first in spring 1934 powered by a 250 PS (247 hp, 184 kW) Hirth HM 8U inverted-V engine, which drove a three-blade propeller.

Although it was outperformed by several other aircraft in the competition, the M 37’s overall performance marked it as a popular choice for record flights. Particular among these traits was its extremely low fuel consumption rate, good handling, and superb take-off and landing characteristics.

The Bf 108A first flew in 1934, followed by the Bf 108B in 1935. The Bf 108B used the Argus As 10 air-cooled inverted V8 engine. The nickname Taifun (German for “typhoon”) was given to her own aircraft by Elly Beinhorn, a well known German pilot, and was generally adopted.
