Bertrand Piccard is a Swiss explorer, psychiatrist, and environmentalist. Along with Brian Jones, he was the first to complete a non-stop balloon flight around the globe, in a balloon named Breitling Orbiter 3.

André Borschberg FRSGS is a Swiss entrepreneur, explorer, pilot, and speaker. He is the co-founder of the Solar Impulse project, the first ever round-the-world solar flight, successfully completed in July 2016. During the Japan-to-Hawaii leg, André broke the world record for the longest solo flight in an airplane of any kind: 117 hours and 52 minutes.

He currently holds 14 FAI world records in the free distance, free distance along a course, straight distance, straight distance predeclared waypoints, distance along a course, duration, absolute altitude, and gain of height. His groundbreaking record: the longest solo flight in an airplane of any kind: 117 hours and 52 minutes.

In 2002 Piccard (left) met Borschberg, who agreed to join him in his quest to travel around the world in a plane completely powered by renewable energy. Borschberg flew as a jet pilot in the Swiss Air Force prior to his work with Solar Impulse. An engineer by education and a graduate of the MIT Sloan School of Management, André Borschberg has solid experience in creating and managing companies. His passion for aviation and his interest in innovative solutions have led him to team up with Bertrand Piccard as CEO, co-founder, and pilot of Solar Impulse.

André Borschberg and Bertrand Piccard (both Switzerland) flew around the world in Solar Impulse 2 between 9 March 2015 and 26 July 2016, powered entirely by energy from the Sun – as recorded by the FAI. Their starting and finishing point was Abu Dhabi in the UAE. Their total journey time was 505 days 19 hours 53 minutes.
