6 Facts You Didn't Know About Olympic Snowboarder Maddie Mastro

Like fellow Olympian Simone Biles, Mastro has experienced the "twisties" while performing dangerous tricks and flips 50-plus feet in the air. In Mastro's sport, this is referred to as "a blackout zone," which is why the double crippler is rarely executed.

"A lot can go wrong when you're flying through the air, but if you're doing it right, you're always seeing," Mastro explained during an interview with Red Bull. "The more you see, the better. So I'm always telling myself, 'Keep your eyes open. Don't go into a blackout zone. Pay attention. And take the world in.'"
