PLOT
For early aviators, conquering the forces of gravity was a daunting challenge. But black aviators had an additional challenge - conquering the forces of racism. Meet the men and women who took to the skies throughout the 20th century, proving to a segregated nation that skin color doesn't determine skill level. From biplanes to commercial jets, and from barnstormers to war fighters, meet the path-breaking pilots who opened the skies for all -- and contributed in countless ways to the development of aviation.
