Ship with explosive cargo
In 1944 the United States cargo ship SS Richard Montgomery ran aground and sank 1 mile (1.6 km) off the coast of Sheerness, with large quantities of explosives on board.[18] Due to the inherent danger and projected expense, the ship and its cargo have never been salvaged; if the wreck were to explode, it would be one of the largest non-nuclear explosions of all time.
The masts of the ship can be seen from the beach at low tide.
