Jump from a balloon
These guys are really crazy ! In the title I don't explain the tricky part, this guy jumps from a balloon and before doing that, he takes off his parachute ! You understood well, this dumb jumps without parachute ! This is really risky, he jumps with two friends and one of them hooks him with his carabiner. Fortunately they succeed and everybody is ok, my heart almost died when I saw the video !
