In 1944, Nazi Germany launched the V1s against the UK. The V1 was a pilotless, jet-propelled flying bomb - the first of its kind in the world and a precursor to the modern cruise missile. The V1 was also the first of Hitler's secret "revenge weapons" which he hoped would change the course of the Second World War. Some 10,000 V1s were fired at the UK. They killed more than 6,000 people and injured 20,000 more. Using archive recordings we hear from civilians who survived V1 attacks and from those tasked to stop the flying bombs.
