Brad Hess, general manager at Vegas Indoor Skydiving, said he spent months practicing and perfecting his technique prior to his successful Guinness World Record attempt Feb. 8, , the Las Vegas Sun reported Tuesday.
"It was just perseverance, really," Hess said. "I was literally practicing two or three times a day, and that resulted in doing 200 to 300 flips a day."
Guinness confirmed Feb. 14 the attempt bested the previous record of 39 full somersaults.
Hess said the most difficult part of the record was getting used to the feeling of spinning in midair, which he likened to "being really drunk and learning to walk straight."
