摘要

BEFORE THE 20TH CENTURY, despite many attempts at building a flying machine, human flight appeared to be the most impossible dream. In 1909, Wilbur Wright described the general belief held before he and his brother made their success public: "When a man said, 'it can't be done; a man might as well try to fly' he was...expressing the final limit of impossibility." With their 1903 Flyer, the Wright brothers defied the common understanding of what was possible.
