Factory explosion

In 1871, an explosion at the factory of Patent Gun Cotton Company, Stowmarket, Suffolk, England, killed 24 people and injured many more It happened in the early afternoon, devastating the factory and left a crater 100-ft long and 10-ft deep. Windows were blown in all over Stowmarket ands roofs damaged, and the explosion was heard up to ten miles away. It was the biggest disaster ever to hit the town. The inquest found that it had probably been caused by sabotage but no one was ever brought to trial. It has been suggested that the findings were a whitewash which helped prevent any criticism falling on the heads of the factory or the inventor of the process. (Guncotton was first patented by Christian Frederick Schönbein in 1846)
