[Was manned flight a victory for rapid prototyping?]( http://m.theatlantic.com/magazine/archive/2013/11/the-man-who-would-teach-machines-to-think/309529/)

> You can credit the development of manned aircraft not to the Wright brothers’ glider flights at Kitty Hawk but to the six-foot wind tunnel they built for themselves in their bicycle shop using scrap metal and recycled wheel spokes. While their competitors were testing wing ideas at full scale, the Wrights were doing focused aerodynamic experiments at a fraction of the cost. Their biographer Fred Howard says that these were “the most crucial and fruitful aeronautical experiments ever conducted in so short a time with so few materials and at so little expense.”
