Gotha Go 150
In January 1937 Major Werner Junck, chief of the LC II, the technical wing of the Reichsluftfahrtministerium responsible for the development of new aircraft, informed various minor aircraft manufacturers such as Gothaer Waggonfabrik, Bücker, Fieseler, Flugzeugwerke Halle and Klemm that they would not get any contracts for the development of military aircraft. He therefore advised them to concentrate in the development of a Volksflugzeug or a small twin-engined plane. As a result, Gothaer Waggonfabrik developed the Go 150.
The aircraft was a twin-engined monoplane with an enclosed cockpit, designed by Albert Kalkert.
The first, D-ERCQ, first flew in 1937. The results of this flight were good, and production began. The aircraft was used to train both civilian and Luftwaffe pilots. The Go 150 was later also used in tests, where it was towed by a Heinkel He 46.
Two prototypes were built, followed by a series of 10. All of them received civil registration. Another series with 10 aircraft was planned but not fulfilled.
The Go.150 established flight altitude records in its class. Firstly, three test attempts in which the aircraft reached heights of 7100 m, 7500 and 7800 m were made. Only when there was full confidence in achieving the record, the Go.150 made the attempt.
On July 5, 1938, piloted by Fritz Platz, after 45 minutes he had reached 7,000 meters, but fell sharply in this rate of climb. At an altitude of 7100 meters, it was only 1m\sec, and in another 700 meters, it decreased to 0.5 m\sec. After 1.5 hours he reached an estimated height of 8,000 meters. After ascertaining the correct indication of the instrument pilot, and after 30 minutes, made a successful landing at its airport. This record was officially recorded FAI.
