Otto Lilienthal published his book
Der Vogelflug als Grundlage der Fliegekunst (Birdflight as the Basis of Aviation) in 1889. This described the basics of modern aerodynamics and aircraft construction. Lilienthal then made many successful flights starting in 1891. However attention then shifted to powered flight after
World War I.
Gliding re-emerged as a sport after the war because the building of powered aircraft was restricted in Germany by the
Treaty of Versailles. The main originator of the gliding movement was
Oskar Ursinus, who in 1920 organised the first contest, known as the Rhön-Contest, on the
Wasserkuppe. Thereafter the contest was held annually. Students of
Technische Hochschulen brought gliders which they had developed and built themselves for testing to these contests. An
esprit de corps developed known as
Rhöngeist. These informal beginnings caused the formation of groups of engineers at
Technische Hochschulen with the aim of scientific and practical education. The first groups were formed in 1920 in Aachen, Darmstadt and Berlin-Charlottenburg, but others soon followed. Many of the first members had been pilots in the German Air Force. However it was the love of flying rather than militarism or nationalism that motivated them. As a result a fraternal spirit was created that has been maintained to this day. During the Nazi period some Akafliegs escaped regulation for a while through the patronage of the
Deutsche Versuchsanstalt für Luftfahrt (DVL), a forerunner of the present-day
German Aerospace Center (DLR), however shortly before
World War II the akafliegs were forced to integrate into the
NS-Deutsche Studentenbund (Nazi-students-federation). The projects at this time mainly had a military application. ==Present day==
