In this week's episode, we take to the skies! In our opening diary, we travel to Kitty Hawk, North Carolina, where a lifeguard witnesses flight history while helping the Wright brothers. Mark then discusses the brother's strong bond, ingenuity, and obsession with flight. We also witness triumph and tragedy during the world's first aerial exhibitions. 

In our What if? scenario, Mark imagines the tragic death of Orville Wright. With the close family devastated, it will be Katharine, their younger sister, who steps up to help Willbur run the family business. She grows the company becomes a super pilot in her own right and even helps train the next crop of American pilots. 

In our final diary, we will be Katharine's co-pilot on one of her flights over New York.

Hit play, and get ready to soar.
