Bufoni strapped a nearly 20-pound parachute to her back and performed a feeble grind -- a combination of a boardslide and a 50/50 grind -- across a pipe that led out the back of the plane at an altitude of 9,022 feet.
Guinness World Records confirmed the stunt earned Bufoni the record for highest skateboard grind outside the back of a flying aircraft.
Bufoni also holds the records for most skateboard street gold medals won at the X Games (street, female), five; most medals won in X Games summer disciplines (female), 12; and largest skatepark built in an aircraft and flown.
"It's crazy to think that I'm the first person to skateboard inside a plane and do a feeble in the air. That's something I didn't know was possible or not.
"I've never skateboarded on an airplane. I didn't know that this project would take such a huge proportion as it took," Bufoni told GWR.
