Based on the design of the Bucker Jungmann, Jungmeister was designed from the outset as an aerobatic aircraft for air shows. The Jungmeister has been used longer for aerobatic demonstrations and competition than any other aerobatic design, for more than 30 years. The Bü 133C racked up numerous victories in international aerobatic competitions.
Its production in 1935. The new plane, which used the tail wing of the Jungmann but was slightly smaller, was named BU-133 Jungmeister (young champion). In its maiden flight, it was flown by Luise Hoffmann, the first woman works pilot in Germany.
Like the Jungmann, the Yungmeister also proved excellent in aerobatic flying, especially in the fast pace of rolling and so quickly became the indispensable companion of all aerobatic pilots. Especially during the pre-war years (when the safety regulations were virtually non-existent) pilots were doing incredible acrobatic low height manoeuvers. The most characteristic manoeuvre was when attaching hooks to the wingtips or rudder of the aircraft to pick up a handkerchief mounted on a stick in the ground. The most renowned stunt pilots in Europe were the Greek originating "Prince of Romania" Constantine Katakouzinos (with 60 debunk Russian planes during WWII) and the also Romanian captain Alex Papana, using the BU-133, in all their demonstrations.
These performances were noticed by the German Air Ministry (RLM) which since it had reviewed the BU-131, it also reviewed the new Bucker aircraft and found it conforming with the standards that were established. As a result, the Luftwaffe purchased a large number BU-133 in 1938, ranking in the aerobatic airplanes of advanced training, equipping its flight schools.
At the same time, other countries also showed interest in the procurement or co-production of BU-133 which forced the firm to enter into co-production agreements with: Switzerland, Spain, Argentina, Romania and South Africa. Fifty-two were manufactured by Dornier for the Swiss Air Force (which kept it in service until 1968). A similar number were built for the Spanish air force by CASA, and were designated the CASA 1-133.
The plane of this collection was manufactured in Switzerland by the company "Dornier-Werke" in Altenrhein. The production license was given in May 1937 and by 1943 they had constructed 49 DO/BU-133 which equipped the Swiss National Air Club and the air force of the country.
This airplane with the serial number S/N: 3 was used by the Swiss Air Force (19 July 1937 to 31 Dec. 1968) as an advanced training aircraft, with the call sign U-56.
On May 29 1969 it received the civil aviation call registration HB-MIN of the Swiss CAA which was retained until May 1971 when it was sold in the U.S. in Ray Strassel taking the N-Call Registry N-133BJ of the Office of Federal Aviation Administration (FAA). Since then and until 1997 it was flying in the U.S. It was purchased by this collection, the Athenian Aviators Collection, in 1997.
Lacking any initial production certificates, it is considered to be "experimental" and has logged 2197 hours of flight since production.
