Si Germania
E si..esatto. Lo chiamarono Windkanone ma chiaramente non fu mai efficace.
The Windkanone (Wind Cannon) was a bizarre German anti-aircraft weapon. It comprised a large barrel, bent upwards at one end, through which an explosive jet of compressed air was ejected upwards by the ignition of a mixture of hydrogen and oxygen. The aim was to knock down low-flying aircraft. Trials showed that a powerful 'slug' of high-velocity air could inflict damage on ground structures, but it was unclear if it would have the desired effect against a small, fast-moving aircraft. In 1945 a wind cannon was installed on a bridge over the River Elbe, but it failed to achieve any results. A te Iscandar!
