Michael Phelps, Usain Bolt, and Gabby Douglas aren’t the only people setting records through amazing physical achievements. In an effort that took over three days, nearly a gross of skydivers took to the skies over Ottawa, Illinois to break the world record in vertical skydiving.

138 divers, to be exact. The previous record was 108, and people traveled from all over the world – France, Sweden, Ukraine, Italy, Russia, and more – to participate.

Over the course of the three days, the 138 skydivers attempted the mid-air feat 15 times before getting it right. The divers jumped from 18,500 feet and formed a snowflake formation, all while falling at speeds or up to 220 mph.
