What Happened

On the morning of October 21, 1966, a coal waste tip on the mountainside above the Welsh village of Aberfan collapsed after days of heavy rain, sending roughly 140,000 cubic yards of liquefied slurry down the slope. The landslide engulfed a row of houses and slammed directly into Pantglas Junior School, where children had just begun their last day of lessons before half-term. In total, 144 people were killed, 116 of them children.

Historical Context

The disaster exposed years of ignored warnings about the tip's location directly above the school, and the resulting inquiry found the National Coal Board guilty of "bungling ineptitude" and "callous indifference" to the danger. It remains one of the deadliest disasters in British history and led directly to new legislation governing the safety of mining waste tips.

Timeline of the Event

Years of warnings about the unstable tip above the village go unaddressed.
Heavy October rains saturate the coal waste tip, turning it into slurry.
Around 9:15 AM, the tip gives way and slides down the mountainside.
The slurry engulfs houses and slams into Pantglas Junior School, trapping students and teachers.
144 people die, 116 of them children; rescue efforts continue for days.

The Five Seconds Connection

In Five Seconds Too Soon, the trio lands in fog-thick hills above the village just before the collapse, with only a bleeding, half-legible chronometer reading and the smell of coal dust to guess where—and what—is about to happen. They watch the slide from the hillside, unable to reach the school in time, and the sound of the valley's screams stays with Megan long after the return.
