Ed Shadle, 66, of Spanaway, Wash., is looking to break the world land speed record of 763 mph this month by driving a jet-powered car across a Nevada desert at 800 mph. He's been preparing for his supersonic quest with dawdling 350-mph test runs.
When adventurer Steve Fossett, 63, vanished Sept. 3 over Nevada, he was scouting sites where he, too, could take aim at the record.
The yen to be the fastest human seems to burn brightest among older thrill-seekers. "If you look around at the demographics of land speed racers, they're all 50, 60, 70 years old," Shadle says.
What is it about speed that seduces so many age 50-plus racers? In this revealing audio slide show, Jimmy and Dena Katz, photographers for the book Salt Dreams (PowerHouse Books, 2006), follow these speed demons as they jet across Utah's legendary salt flats during this year's Bonneville World Finals.
