Beginning in 2015, the world’s very first attempt to fly around the world in the world’s first solar plane took place. The plane’s name is Solar Impulse 2.
Pilots Bertrand Piccard André Borschberg, who were also the founders of this project, flew from from Abu Dhabi in the United Arab Emirates in March and have been flying since, obviously with stops. The plane was scheduled to return to Abu Dhabi back in August 2015; however, in June of that year, after flying through all of Asia, they hit Hawaii and the aircraft batteries suffered major thermal damage that took months to repair. Finally, on April 21st of this year, the Solar Impulse resumed its flight and landed in California on April 23rd, and on May 2nd, started on its way to Phoenix, Arizona.
