Three key points from the document:
1. The document describes the Piper Alpha disaster which occurred in 1988 and killed 167 men. It profiles Shane Gorman, whose father died in the disaster, and the lasting impact it had on his life.
2. It also profiles Gary Calder, whose father Harry survived the Piper Alpha disaster but was profoundly changed by it. Gary notes that his father took on a lot of guilt for surviving.
3. The disaster had wide-ranging impacts on the families of the victims. Shane in particular discusses the "chaos" and feelings of helplessness in the aftermath. Both men now work in oil and gas safety roles in honor of their fathers.
