With Leonardo 's assistance, Skydweller Aero is developing an unmanned long-endurance solar-powered platform based on the Solar Impulse 2 aircraft.
Between March 2015 and July 2016, the Solar Impulse 2 made a round-the-world journey that was undertaken by pilots Bertrand Piccard and André Borschberg in 17 flights, including a flight from Nagoya in Japan to Hawaii that took nearly 118 hours.
