Bertrand Piccard and André Borschberg, captivated by the spirit of great expeditions of the past, partnered to make the first flight across the world in a solar-powered plane that produces no pollution.
Storing solar energy in batteries, the Solar Impulse is capable of staying aloft indefinitely. Solar Impulse 2 is a solar-powered aircraft equipped with more than 17,000 solar cells that weighs only 2.4 tons with a wingspan of 235 ft.
The journey took a very long time—505 days to fly 26,000 miles (42,000 km) at an average speed of about 45 mph However, as Piccard and Borschberg learned, this didn’t make the adventure easy — or require any less intrepid heroism from the co-pilots.
