In the late 1970s, Paul MacCready led a team that won both the first (and later the second) Kremer Prize. The £50,000 award was set up in 1959 as a challenge to develop human-powered flight. In August 1977, cyclist Byron Allen completed a figure-eight course in the Gossamer Condor. In 1979, he crossed the English Channel in the Gossamer Albatross. Amazing feats, still awesome more than 35 years later – and although these are old stories, this example comes to mind often. Not just because of what they did, but because of the way they did it.
