"It's a dream come true," tweeted Swiss pilot André Borschberg, 62-year-old CEO of the Solar Impulse project, who has spent the better part of the week in the cramped cockpit of his aircraft, sleeping for only 20-minute stretches at a time. After 77 hours, he had surpassed aviator Steve Fosset's record nonstop flight back in 2006. Meanwhile, the Solar Impulse 2 was flying over open water with no nearby landing sites in the event something had gone wrong, the so-called "Earhart Leg" of the trip, named in reference to American aviator Amerlia Earhart, who disappeared along a similar route.
