Brean Down seemed an ideal testing site for secret weapons. A rail track was built and the so-called bomb was mounted on a six hundredweight trolley propelled at 200mph along a caterpillar track by 12 powerful rockets. The aim was to propel the trolley at high speed into buffers. The impact would fling the bomb far out to sea. But the whole lot - trolley, buffers and all - actually went flying off into the Channel, then did a sharp right and came back inland into a local farmer's chicken run!
