This MrBallen episode features three true stories of divers who underestimated underwater dangers. The first recounts a fatal drift dive in New Zealand’s French Pass, where a tide miscalculation pulled seven divers into deadly whirlpools, killing two. The second details a 1983 tragedy at Texas’s Jacob’s Well, where one diver drowned after getting trapped in a false chimney while exploring the sealed fourth chamber. The final story describes a 1955 incident at Georgia’s Radium Springs, where a diver drowned just feet from his safety line after becoming disoriented in zero visibility.
