"Without question, flight is represented by countless heroes who have stirred greatness in others. It was a dream that had been waiting to be realized for thousands of years, and chased by countless visionaries, scholars and brave souls. But even as the mass of collected knowledge came to a crucial turning point, it was not until the ingenuity of the Wright Brothers that the puzzle of powered flight was solved. Discovery requires deep understanding, constant interpretation of knowledge and unbridled persistence."
It is part of a speech given by Marion Blakey on December 17, 2002 at the Air and Space Museum for the Centennial of Flight Kick-Off event. Unfortunately I can't find the full text of the speech (for free at least, it is part of a book you can buy for \$5 used, or \$108 new). Marion Blakey was the 15th FAA Administrator from 2002 to 2007.
