Overview The Grunau 9 was a German single-seat
trainer glider, among the first in a group later known as
primary gliders. It was developed by
Edmund Schneider based on the
Espenlaub primary glider, which itself was influenced by
Alexander Lippisch's earlier designs, including the glider (English: 'Damn it' or 'Devil take it'). The German phrase is linked to two Swedish students in Lippisch's
Wasserkuppe workshops, who would often curse using whenever they inadvertently struck their hands with a hammer. The Grunau 9 was produced in significant numbers and sold widely. However, no documented incidents of severe injury resulting from this structural feature have been recorded.
Legacy In the succeeding
SG 38 model, the pilot's seating position was revised, placing them in front of the lattice framework. The Grunau 9 was produced in large numbers and sold widely over several years. At least one
Dutch-registered Grunau 9 remained in operation after
World War II. ==Aircraft on display==
