Nine Atmospheres — The Byford Dolphin Decompression Disaster
Every story in here actually happened. That's the part that should scare you. On November 5, 1983, aboard the drilling rig Byford Dolphin in the Norwegian North Sea, a routine saturation diving operation ended in one of the most catastrophic decompression accidents in history. In a fraction of a second, a chamber holding five men went from nine atmospheres of pressure to one. Four divers and a diving tender died instantly. This is the story of what happened inside that chamber — and what it revealed about the invisible forces we work alongside every day.
