Gaynor Madgwick remembers her excitement that morning in 1966. It was the last day of term, and she and her siblings would be let out of school at lunchtime.
They had got up, three to a bed in their little terraced house in Aberfan, a village in south Wales. Their mother had, as usual, already lit the coal fire. Carl, the only boy among the six children, didn’t want to go to school, but they were sent out with some money to buy a few sweets from the shop on the way.
