The rest of the book is about the further development of aircraft, not much about the Wrights .p342 TAH: "Wilbur drew on his recent background by conceiving that an airplane was to amount to a flying bicycle." .p343 TAH: "The Wright brothers were brothers, which also contributed to their success. They could argue the issues in full. Indeed, they spoke only half in jest when Wilbur converted Orville to his point of view, while Orville convinced Wilbur that he had been right. Such interaction was essential; it enabled each man to challenge the other, to break an unproductive line of thought, and to compel one another to justify lines of reasoning in detail. No one else had that."
