After waiting out wind gusts, and undergoing a speed check, Zink dropped in and threw the historic backflip with ease over the dirt-to-dirt jump. In the end, his official jump record stood at 100 feet, 3 inches. "Cam, welcome to the Guinness World Records family: you are officially amazing," said Guinness World Records representative Alex Angert, after verifying the backflip length.
