It was inevitable that tragedy would strike. On October 31, 1941, three men blasting through the sandstone in Kingsford Country Park in Worcestershire, England, were caught as large chunks of rock rained over them. The explosions had caused portions of the roof to collapse over their heads. By the time rescuers cleared the scene, it was too late. All three were dead.
