The Bücker Bü 181 Bestmann (Best Man) is a two seater, single engine trainer aircraft built by Bücker Flugzeugbau GmbH in Johannisthal, Berlin and extensively used by the Luftwaffe in World War II.



The prototype Bü 181 (D-ERBV) made its maiden flight in February 1939 with Chief Pilot Arthur Benitz at the controls. After thorough works and official flight testing by the Reichsluftfahrtministerium (RLM) the Bü 181 was nominated to be the standard primary trainer for the Luftwaffe. Series production of the Bü 181 commenced in 1940/41. The types were designated A to D with only slight variations between each and could be powered either by the Hirth 500A or 504 engine.


The Bü 181 Bestmann was powered by a 105 hp four cylinder Hirth HM 504A piston engine. The Bü 181A aircraft was a single engine low wing monoplane with fixed undercarriage, air-cooled 4-cylinder HM 500 A engine, split flap, twin controls and two adjustable seats arranged side-by-side. The cabin section of the fuselage was of a tubular steel frame construction whereas the rear of the fuselage had a wooden shell. The wing assembly and tail unit were also of wooden shell construction. All the rudders, elevators and ailerons had wooden ribs and are covered in fabric.

The aircraft was designed for training flights, pleasure trips and aerobatics. Its strength corresponded to Stress Group 5 with a limited load (single occupancy) and Stress Group 4 fully laden.


The Bücker factory at Rangsdorf built most of the Bü 181's, but because of demand was forced to license the design to the Fokker Company in the Netherlands, who subsequently built 373 of the type for the Luftwaffe all of which were delivered by the end of 1943.

Production of both the Bü 181A and the slightly modified Bü 181D was begun by Fokker in Amsterdam in 1942 and its total wartime production was 708 aircraft. Between 1943 and 1945, Hägglund & Söner AB in Sweden built 125 Bü 181's with the Hirth 500A engine with the Swedish military designation Sk 25.

Just prior to the German withdrawal from Czechoslovakia, production of the Bü 181D was initiated in the Zlín plant at Otrokovice, and production continued after the war, as the C.6 and C.106 for the Czechoslovak Air Force and as the Zlín Z.281 and Z.381 in various versions for civil use. 783 aircraft were built.

During the 1950s the Heliopolis Aircraft Works of Egypt acquired a Czechoslovak licence to produce the Bestmann in versions similar to the Zlín Z.381 with a 105 hp Walter-Minor engine. It was produced for the Egyptian Air Force as the Gomhouria (meaning "Republic") and subsequent versions were supplied to other Arab air forces. At least 300 Gomhourias were built.[1]

In all, 3,400 aircraft were built but only a handful survive today.


Although built as a primary trainer for the Luftwaffe, the type also performed other duties such as communication, glider towing, and even transporting Panzerfaust weapons (an armour piercing rocket projectile with a hollow-charge warhead used as an infantry weapon against tanks.)[2]

A Bücker Bü 181 'Bestmann' was used in the movie The Great Escape. It was flown in the movie by James Garner with Donald Pleasence as his passenger.

Test pilot, and sister-in-law of Claus von Stauffenberg, Melitta Schenk Gräfin von Stauffenberg was flying a Bücker Bü 181 when she was shot down and fatally wounded in 1945. [3]
