Solar Impulse traveled around the world, breaking the journey down into 17 legs, spending a total of 23 days in the air. The plane, powered by 17,000 solar cells, traveled 42,000 kilometers (about 26,100 miles) in a little more than a year. Its trip across the Atlantic Ocean from New York City to Seville, Spain, alone took approximately 90 hours to complete, traveling at 140 km/h (about 87 mph). The plane’s longest trip was from Japan to Hawaii, which lasted almost five days.

Bertrand Piccard and André Borschberg alternated piloting the solar-powered plane. On the ground, they were helped by a team of 30 engineers, 25 technicians and 22 navigation controllers.
