Two pair of pioneering brothers helped free mankind from Earth. They were working privately without government assistance, and their story cover the 20th century in the first episode, "The Wings of Man". Orville and Wilbur Wright broke the bonds of earth and made the first controlled flight in 1903. Over 80 years later, Burt and Dick Rutan made history of their own with the revolutionary Voyager, making the first around-the-world non-stop flight.
