English Translation

The balloon starts to rise again due to this release of ballast. This game, which depends on the external air pressure, i.e. on the altitude of the flight, is now continuing until after an intended flight time. After a certain flight route, the fuse burns through the twine, which keeps the lower flap in horizontal position. The flap falls down in slanting position and the droppipe no longer protrudes into the pot filled with kerosene. The connection between the liquid in the pot and the fallpipe is therefore interrupted. By ingress of air into the drop pipe and thus into the balancing tank, the lifting effect stops and the balloon starts to sink at normal gas discharge. During the slow descent, it stretches over the ground for a certain time at 200 - 300 m altitude and disturbs the high voltage lines in flight direction by short circuit by means of the hanging wire. In the period from 2l.3.42 (beginning of the arrivals) to 15.4.42 366 pieces of these hostile interference devices were found in the Reich area and in the occupied East and West areas. The damage caused by the balloons to high-voltage lines are temporarily low. Meanwhile, another high-tension arrester has become known, however, about which more details are not yet available. These are the same balloons, on which, however, a wooden disc is mounted horizontally in place of the barometric height compensation device. Under this disc, a series of sand bags are attached, which are brought to waste successively by a slow-burning fuse. Underneath it is probably attached to a longer cord a jamming body filled with explosives. By driving the balloon at low altitude before the wind, the carrier line of the disruptor comes into contact with the power line, pulls the body up to the line through the wind pressure and detonates at the contact of the detonator at the line.
