A special edition of Destination Tomorrow™ looks back at the first century of powered flight. See how two relatively unknown bicycle makers from Dayton, Ohio beat many of the world's foremost thinkers to become the inventors of the airplane. Correspondent Jennifer Pulley speaks to researchers who are working on new designs that could change air travel. New aircraft shapes, cleaner burning fuels and new materials could be the first steps in the next revolution of aircraft design. This program consists of two exciting segments. In the "Behind the Scenes" segment, viewers will learn how throughout history man has always been intrigued with the idea of flight; in the "How it Works" segment, viewers will go back to the morning of December 17, 1903, where history was made off the dunes of Kitty Hawk, North Carolina.
