The explosion heard by millions

In 2005 thousands of tonnes of petrol ignited at a fuel depot 40 kilometres North-West of London. The explosion was the largest in the UK since the end of the WWII. The blast, which severely damaged surrounding homes and properties, was reportedly heard in Holland. Despite the enormous amount of damage, nobody was killed. The fire destroyed large parts of the depot, leading to shortages of fuel at petrol stations in the weeks that followed. Five firms were eventually fined millions of dollars for safety failures that led to the blast. Greg Smith tells Witness History what it was like to be inside the depot at the time of the explosion.
