Aberfan: A Story of Survival, Love and Community in One of Britain’s Worst Disasters, written by survivor Gaynor Madgwick, is an excellent source in which Madgwick spoke with many people who were there on the day, presenting a fascinating look into the psychological effects of a disaster on a community.
Aberfan: The Untold Story is a great comprehensive documentary which covers the disaster and the investigation in the aftermath.
Surviving Aberfan is the documentary released for the 50th anniversary of the Aberfan disaster. It features many interviews with survivors, rescuers, and families, many of whom have not been interviewed before.
Aberfan: The Green Hollow is a lovely dramatic film to commemorate the 50th anniversary of the disaster. Pant Glas (the name of the school destroyed by the collapse) means “green hollow” in Welsh. This is an incredibly well-done film which recreates the disaster with lots of beautiful camera shots and a fantastic cast.
