Today was the fiftieth anniversary of one of the saddest days in Welsh history. Wales is a country that has seen more than its fair share of mining disasters but they usually involved the men, the Welsh miners, explosions, and cave-ins. On this day, 21 October 1966, the tragedy was even worse, as the 144 people who died included 116 children, happily attending the village school when a colliery spoil tip collapsed, sending a huge landscape down the hillside, obliterating everything in its path. Today, in Wales, we remembered the children of Aberfan.
