Göppingen Gö 4

The Göppingen Gö 4 (or "Goevier") was a German sailplane of the late 1930s used for training pilots. Its most notable features included a side-by-side seating format and dual controls, making the plane ideal for use as a trainer. It boasted average performance, compared to other gliders of the day, and was advertised as making the process of learning to fly sailplanes easier.

The Gö 4 had been designed primarily as an improvement over the Gö 2, which sported inline seating rather than the more instruction-friendly format of the Gö 4. Despite the alterations, the fuselage was kept as narrow as possible. The Gö 4 was produced in Kirchheim, and was first flown in 1937.
