The wave rushed through the village, destroying everything in its path.
Homes were smashed apart.
Roads vanished beneath the torrent.
And then the avalanche of coal waste struck Pantglas Junior School.
Inside, children were sitting at their desks, beginning their lessons.
In a matter of seconds, classrooms disappeared beneath a wall of mud.
The school was engulfed.
Panic spread across the village.
Parents heard the noise and ran toward the school.
Miners abandoned their work underground and rushed to help.
