On the 21st of March we looked at the bouncing bomb in history. Their job was to break the German dams. The dams in Germany were very important because they could power the factories that made bombs. Sir Barnes Wallis invented the brilliant bomb. He tested it out in his garden with a catapult and a pond. They weighed 9000lb and was 60 inches long and 50 inches diameter. The pilots had to fly at the right height, the right speed and the right angle. The bombs rolled on the dam and sank. When the pressure built up it exploded. The pilots who destroyed the dams were called the Dambusters.
