In northern England, 37 rescuers searching for mining disaster survivors are killed in a second explosion

At the Oaks Colliery near Barnsley in Yorkshire, the day before, a massive explosion and ignition of flammable gas raced through the underground galleries , killing hundreds of miners. This following morning, dozens of volunteers descended to search for survivors but they themselves were caught in a second huge explosion that killed 37 more miners.  The total death toll over the two days came to at least 367 men and boys, and the Oaks Disaster remains to this day the deadliest recorded English mining disaster.  (By John Osborne)
