IDEA 1
Two brothers dreamed of flight
McCullough tells the story of Wilbur and Orville Wright, two brothers from Dayton, Ohio, who had no university education but taught themselves engineering. Working together in their bicycle shop, they set out to solve the problem of human flight.
IDEA 2
Birds inspired their ideas
The brothers studied how birds balanced and turned in flight. Wilbur noticed that birds twisted their wing tips, which inspired the brothers' idea of wing warping to control an aircraft.
IDEA 3
Bicycles taught them balance
McCullough explains that running a bicycle business gave the brothers mechanical skills and an understanding of balance and control. These lessons helped them design aircraft. Practical skill mattered more than formal degrees.
