Trivia, insights & behind the scenes
This 1979 BBC documentary helped popularize cave diving as an extreme sport, though most viewers probably just felt grateful to stay above ground.
Yeadon and Statham were genuine British caving legends; Bear Statham's nickname came from his habit of hibernating in caves for multi-day expeditions.
