Skydiving specialist Michel Fournier plans to break the world record for the highest skydive ever attempted. If all goes well, he will jump from a balloon at an altitude of around 131,000 feet, or 25 miles above Saskatchewan, Canada. At around 115,000 feet his body will blow through the sound barrier. At 102,800 feet, he will pass the current world record for highest altitude jump.

If exceeding Mach 1 doesn’t tear him apart, he doesn’t go into an uncontrollable spin and die, and he manages to survive lethally low temperatures, pressures, and oxygen levels, his name will go down in the history books.
