The Solar Impulse 2 is a solar-powered plane that has been flying around the world since March. Back in May, it was set to make its most ambitious journey yet, a 5,061-mile trip from Japan to Hawaii. Unfortunately, though, Pilot Andre Borschberg's initial attempt was unexpectedly cut short (as has happened before), this time due to inclement weather. Now, several weeks later, he's finally accomplished his mission. Borschberg landed in Kapolei, Hawaii on Friday, following a five-day, 118-hour flight from Nagoya -- the longest-ever solo nonstop flight. The previous record was 76 hours.
