In 1966, a coal waste tip collapsed above the Welsh village of Aberfan.
The avalanche of mining debris buried homes and the local school, killing 144 people — most of them children.
The tragedy exposed serious failures by the National Coal Board and led to major changes in how mining waste was managed across the UK.
The Aberfan Disaster remains one of the most heartbreaking events in British history.
