While flying the sun-powered plane Solar Impulse 2, Swiss pilot André Borschberg has broken the record for longest solo flight without refueling. 
Though he surpassed the previous title-holding duration at 76 hours, he’s still got a ways to travel before he touches down at his Hawaiian destination. 
By the time the journey is completed, he will have been in the air for 5 days. 
He departed from Japan on June 28th.
