It's an old saying, what goes up must come down.
Yet in a first, 70-year-old Ivan Trifonov flew this hot air balloon down first, into a cave 200 meters deep in Croatia's Velebit mountains.
The experienced pilot touched the cave's bottom and then flew back out.
SOUNDBITE: Austrian adventurer Ivan Trifonov saying (German):
"This was a very difficult thing to do. A very difficult project. One must have the right balloon, the right weather and the right support. It was very hard, and I don't think anyone else will ever repeat this feat. I sincerely doubt it."
The inspiration for his adventure was Journey to the Center of the Earth, a book by the famous author Jules Verne.
Trifonov's flight came exactly ten years after fellow Austrian adventurer Felix Baumgartner had pulled off a parachute base jump on the same spot.
