Most wingsuiters jump off cliffs or out of planes, but if you want to go really high, a hot air balloon is another way to launch.
The previous world record for wingsuit flying without oxygen was set last year by a Swiss man named Romeo Lang at 26,247 feet. Zhang Shupeng challenged his record in Inner Mongolia.
After Zhang jumped out, he flew vertically for the first 328 feet, and then adopted a spiral style for 6,500 feet. Then he switched back to vertical flight before opening his parachute at 2,600 feet.
During the dive, Zhang lost control of his hands due to lack of oxygen, although remained completely conscious.
Also the dramatic change in elevation caused intense pain in his ears.
Zhang said all his reactions slowed down, and even deploying the parachute was completed in slow motion.
