On May 8, 2013, Alan Eustace, then the 56-year-old senior vice president of knowledge at Google, jumped from an airplane18,000 feet above the desert in Coolidge, Arizona. Anyone watching would have witnessed an odd sight: Eustace was wearing a bulky white space suit—the kind nasa astronauts wear. He looked like a free-falling Michelin Man.
