Otto Lilienthal was a German pioneer of aviation who became known as the "flying man." He was the first person to make well-documented, repeated, successful flights with gliders. Photographs of his attempts were published worldwide, sparking a fever over the possibility of powered flight in many, including Orville and Wilber Wright.

Capitalizing on the national bicycle craze, the Wright brothers had opened a repair and sales shop, and eventually began manufacturing their own brand. Wilbur, particularly, toiled day and night at the bike shop over the possibility of building a flying machine, and the brothers began putting the money from their successful business into a research project.

On this episode of America's National Parks, the Wright Brothers, the invention that would change the way we travel, and the National Memorial that bears their name.
