Seldom are geotechnical topics the subject of movies or television shows. A very recent exception is an episode from the third season of “The Crown” on Netflix, entitled “Aberfan”. It depicts, relatively realistically, the October 1966 disaster when 230,000 m3 of coal waste failed and flowed rapidly into the town of Aberfan, Wales killing 144 people, 116 of them children.
To learn about the disaster, and the conclusions of the Aberfan Disaster Tribunal, see https://www.vulture.com/2019/11/aberfan-disaster-the-crown-season-3.html, https://en.wikipedia.org/wiki/Aberfan_disaster and Aberfan Disaster Tribunal.
We know of several Canadian geotechnical professionals who entered the geotechnical field in the late 1960s and early 1970s because of this tragedy.
