2 - Subject: Enemy sabotage by high-voltage devices. Reference: Decree of 31.3.42 - IV A 2 - B.No. 150/42 g.- concerning enemy sabotages by entering balloons with fire devices. Attachments: 2 sketches. 2 In cooperation with the Reichsanstalt der Luftwaffe für Luftschutz, the real purpose of the B:llone, which was mentioned as an enemy samotage device, has now been clarified. The purpose of this device is to produce short-circuits on high-voltage lines and thus cause disturbances in the electrical power supply. The device consists of a rubber balloon with a diameter of 2 - 3 m, a plate aid for barometric height compensation, about 200 m hemp cord and about 100 m steel wire of 1.8 mm thickness. The balloon is equipped with a filling nozzle, closed bar by a rubber ball valve, and an overpressure valve. On the rubber plate of the pressure relief valve a string is attached, which leads through the bale and through a tulle to the outside. According to the intended maximum flight height, the length of the binding thread is determined on the basis of a fabric customs dimension attached to the tulle and the thread is provided with a knot at this point. If the contents of the balloon expand under the effect of thin air layers, the thread is stopped at the tulle according to the length of the knot and the pressure relief valve is opened and gas released under the pressure effect of the balloons. The baro-metric height compensation device is attached to the filler with a rubber stopper. The design of the unit made of tinplate is based on my
