There are things that the majority of people will never do. Parachute jumping is one such thing - you need to be absolutely fearless and daring for that.
But what about swimming in ice-cold water in the middle of winter? It is also a very specific way to entartain yourself. Definitely not for everyone.
What if you combine both things to complicate the mission - jump with parachute into the cold water where a hole has been carved out of the ice? Sounds crazy, huh?
And I’m not talking about people with a death wish - on the contrary. It’s about the real pros who have the guts to do such things. Watch yourself how Russian paratroopers go ice swimming from the height of 1500 metres.
