Official records aren't kept of BASE jumps, but Aiello estimates that 10,000 people around the world have jumped at some point. The number of weekly BASE jumpers is probably about 1,000 and another 1,500 people may jump a couple times a year.Aiello stopped counting his BASE jumps after his 1,000th in 2003.ost regular BASE jumpers have probably flown in a wingsuit at some point, but only a small number regularly jump in one, Aiello said. Of that number, only 20 to 50 people in the world practice the type of terrain flights Potter did, flying through canyons and just inches from rock walls and treetops.
