Diving into the Unknown

Documentary: Diving into the Unknown

Having recently dived into the 21st century (with a Netflix subscription), I looked up this Finnish documentary as soon as it became available. It covers events that took place early in 2014, when a group of Finnish cave diving friends started a traverse of a massive, deep cave system in Norway. Two did not surface from the dive.

The Norwegian police, advised by Rick Stanton, a well-regarded British cave diver, closed the cave and announced that it was too dangerous to attempt to retrieve the men’s bodies. Their dive buddies, who had pioneered exploration of the more than 100 metre deep system and felt they knew it like the back of their hands, disagreed. They also felt a duty toward their friends, and therefore planned a mission (illegally) to retrieve their bodies.

Their dives were filmed for this documentary, which features interviews with the surviving divers and another of their friends who trained some of them as cave divers, and accompanied them on their mission. Whether events mirrored those that took place at Boesmansgat in 2005, or whether the ending was quite different, I’ll leave you to find out.

Unless… you read this excellent article¬†from the BBC, before watching the documentary. It will reveal the outcome of the body retrieval dives, but it may also enhance your enjoyment of the film. A chance to study a map of the cave system, which featured in the film but was introduced too late for it to be truly helpful, and a chance to familiarise oneself with the difficult Finnish names, may be of benefit.

This is hardcore diving, to incredible depths, on rebreathers, in overhead environments, and under ice (to start the dive, the men cut a hole in the ice covering a lake surrounded by snowy hills and bare trees). Most of us will never do anything like it. The scenes filmed inside the cave range from serene clarity to heart-stopping moments of claustrophobic intensity as the divers work through obstructions and labour to free their friends’ bodies. Even though this is likely not aspirational for many of us, the questions raised by the men’s mission, especially whether it was wise to go back into the cave at all, make for some interesting discussion.

See the documentary on Netflix, or get the DVD here (South Africa) or here. Here’s the official trailer:
