After the Cretan episode, experiments in the glider transport of large numbers of troops into simulated enemy territory were begun at the Experimental Department (Versuchsabteilung) of Berlin. With promise of success, the experiments were continued and intensified on the airfields of Stendal and of Lager Linde near Grossborn. In mid-1942, secret experimentation with gliders carrying as many as 50 or more men were being conducted officially on the airfields of Stendal, Hildesheim, Halberstadt, Hanover, and Berlin. Tests in carrying all-purpose vehicles and tanks have been frequent.
