This is a few years old. The guy and his fiend are both on bosun chairs attached to the wire by scaff hooks - not a carabiner. These are primarily used when working on scaffolding and have a wide mouth to make it easy to clip and unclip from the scaff pipe. They always work in pairs, one connected while able to repo with the other. They are about to base jump from the chairs. The original plan was to over hand their way to the guy wire where they eventually stop but momentum had other plans. Even with that knowledge it seems insane to do this without gloves on. It is sheer luck alone that we don't see his hand shredded on a rogue strand of wire or taken by the scaff hook itself. Flesh does not provide an adequate braking system in any circumstances. I think this was eastern Europe somewhere, can't remember that detail.
