In 1944 the V-1s and V-2s, Hitler’s ‘vengeance’ weapons, were regarded by the Allied leaders in London as the single greatest threat they had faced. It was feared that these flying bombs and rockets might turn the tide of war once again in Germany’s favor. Yet, little more than half of these missiles hit their targets, some failing to explode. Their wreckage lay across the southern half of England or in Europe, with contents liable to sudden and deadly ignition. It was the job of specialist Bomb Disposal teams to render the V-weapons safe and uncover their secrets. This is their story.
