He Wrote the Rules That Kept Divers Alive. Then a Cave Kept Him | 1994

In April 1994, the most experienced cave diver in history disappeared into a flooded sinkhole in Mexico. He never came back. Six months later, a 20-year-old diver went too deep in a South African cave and never came back either. For ten years, the South African cave kept him — until another diver descended to bring him home. This is the story of three men, two caves, and the year that connected them all.
