 Official construction began in the late summer under the code name "Höhenflugzentrale Deutsche Verkehrsfliegerschule" (Altitude Flight Central of the German Airline Pilot School).By January 1935 enough construction was completed for the airfield to open.It was, however, a school only in name because the restrictions of the Treaty of Versailles, which ended World War I, did not permit Germany to have a military air force.
