“The experimental Solar Impulse plane, which has made several trips since its maiden flight in 2009, will take off on May 1st on a transcontinental tour split in five stages. ’We are ready to do this flight across America,’ said Solar Impulse co-founder Andre Borschberg during a press conference at a hangar in Mountain View, near San Francisco. A non-stop flight would take approximately three days travelling at the aircraft’s cruising speed of around 43 miles (70 kilometres) per hour. ‘We have limited ourselves to fly a duration maximum of 24 hours,’ said Borschberg, who will share the piloting duties with Solar Impulse president Bertrand Piccard.”
