Normally, when you imagine a hot air balloon, you envision sailing through the clouds with nothing between you and and the wind on your face. But for Ivan Trifonov, this fearless adventurer had other plans to take his zeppelin where no one has ever gone before. Trifonov is a 70-year-old Austrian daredevil that holds four guinness world records and Is about to set a new one by being the first to pilot a hot air balloon underground. Here is a video of him descending down one of the most treacherous caverns in the world, the 675-foot Mamet Cave on Velebit Mountain in Croatia.
Congratulations Ivan you are Like A Boss… Keep it up!
