Solar Impulse - Milestones

Milestones

On 21 March 1999, after 19 days, 21 hours and 47 minutes in the air, Bertrand Piccard and Brian Jones’s Rozière balloon landed in the Egyptian desert, ending so the first non-stop circumnavigation of the earth in a balloon. News desks from New York to Beijing and from London to Singapore raved over this exploit, which made the front headline in the New York Times.

On landing, just 40 kg remained of the 3.7 tons of the liquid propane with which the two had taken off from Château d’Oex, Switzerland. Realizing that a lack of fuel could have doomed the adventure, Bertrand Piccard promised to himself to repeat his circumnavigation of the world, but next time without fuel or polluting emissions. From this promise the Solar Impulse project was born.

In André Borschberg he found a partner and on 29 June 2004, Solar Impulse was officially founded by Bertrand Piccard and André Borschberg.
