In the past, the glider pilots were pulled down the slope with the cable winch to start. The buildings in the Masseldorn were getting closer and closer and it was inevitable that the cable that had ended could not be pulled in quickly enough because of the large steel ball and the parachute, which probably did not always open you . So hit the ball with the rope on land and a house. Since then, the slope has been pulled up towards the glider building, tower, Bismarkturm.
