What a breathtaking documentary this was. Andrzej Bargiel first climbs solo, without oxygen, to the top of the 8611 metres high K2. His fellow climbers have a drone with them that turns out to be very useful and shows beautiful images. From the top, he puts on his skis and skis up to basecamp at 5000 m. I am not into this kind of mountaineering myself, at most a volcano in Bali, but I found this very beautiful to watch.
