Rings um die Reichshauptstadt zeiht sich in weitem Bogen ein breite eiserner Schutzwall, der sichere Hort der Reichshauptstadt vor feindlichen Angriffen aus der Luft. Tag und Nacht sind die Männer der Luftabwehr, sei es am Flakgeschütz, sei es am Scheinwerfer oder am Horchgerät, sei es als Besatzung unserer schnellen Jäger, auf der Wacht. Wir bringen Aufnahmen von dem Besuch unseres Bildberichterstatters bei der Flakartillerie. English: "Berlin flak protection"
This is an acoustic aircraft detection device. In World War 2, before radar was developed, these devices were used to detect approaching enemy aircraft by listening for the sound of their engines. It consists of 4 acoustic horns, a horizontal pair and a vertical pair, connected by rubber tubes to stethoscope type earphones worn by the two technicians left and right. The stereo earphones enabled one technician to determine the direction and the other the elevation of the aircraft."All around the capital in a wide arc lies a broad iron line of defense, the safe haven of the imperial capital from enemy attacks from the air. Day and night the men of the air defense, whether on anti-aircraft gun, searchlight, or listening device, are on the watch. We take photographs of the visit of our reporter to the anti-aircraft artillery. |
