In 1944, London faced an unprecedented and terrifying threat from a completely new weapon - the V2 rocket. Travelling at over 3000 miles per hour, more than four times faster than the speed of sound, no warning of its approach could be given and no defence was possible. Find out what happened when a V2 hit a crowded pub and how all those killed and injured are now commemorated on a blue plaque. This is not just a story from history, it's a story about what one person can do with a great deal of perseverance.
