With their former trust in the calculations of Lilienthal and Chanute shattered, the brothers set out that autumn of 1901 to crack the code of aeronautics themselves. It was a brave decision and a crucial turning point. Of primary importance was to find a way to achieve accurate measurements of the “lift” and “drag” of a wing’s surface, and the ingenuity, as well as patience, they brought to their experiments were like nothing done by anyone until then. For three months, working in one of the upstairs rooms at the bicycle shop, they concentrated nearly all of their time on these “investigations” and with stunning results. They devised and built a small-scale wind tunnel—a wooden box 6 feet long and 16 inches square, with one end open and a fan mounted at the other end, and this powered, since the shop had no electricity, by an extremely noisy gasoline engine. The box stood on four legs about waist high. Although a wind tunnel had been used by an English experimenter, Francis Herbert Wenham, as early as the 1870s, and by several others since, including Hiram Maxim, their tests were nothing like those of the brothers, who proceeded entirely on their own and in their own way.

A clever follow-up study by an international team of scientists recruited a group of young women, all with normal visual acuity but some who had poor depth perception and others with good depth perception. Each woman had a catching pretest—in which she had to snag tennis balls shot out of a machine—followed by more than 1,400 practice catches over two weeks, and then a posttest. The women with good depth perception improved rapidly during the training, while the women with poor depth perception didn’t improve at all. Better hardware sped the download of sport-specific software.

“Look, winning has a price. And leadership has a price. So I pulled people along when they didn’t want to be pulled. I challenged people when they didn’t want to be challenged. And I earned that right. … You ask all my teammates: ‘The one thing about Michael Jordan is he never asked me to do something that he didn’t (bleeping) do.’ When people see this, they’re going to say: ‘He really wasn’t a nice guy. He may have been a tyrant.’ Well, that’s you. Because you never won anything. I wanted to win. But I wanted them to win and be a part of that as well.”
