Lengede-Broistedt mine flood in Germany

A reservoir dam collapse at an iron mine in Breustadt, Germany, trapped 43 miners, with three finding refuge in an air pocket. A massive rescue effort was launched, drawing parallels to a similar incident in Hazleton, Pennsylvania. Communication was established with the trapped miners, who were under heavy air pressure. The rescue involved drilling a shaft with extraordinary precautions to prevent a sudden air escape. After more than a week of effort, the rescue reached its climax, saving the trapped miners.
