A solar-powered plane has made history by flying from Japan to Hawaii, a journey of almost 6,500 kilometres. The plane is called Solar Impulse 2. Solar panels that cover the plane convert the sun's rays into power. Scientists hope that all airplanes in the future will fly using solar power. Solar Impulse 2 landed in Hawaii after a 118-hour flight across the Pacific Ocean. Swiss pilot Andre Borschberg tweeted about his feelings after arriving in Hawaii. He wrote: "Just landed in Hawaii with Solar Impulse….It's a dream coming true." The flight broke the record for the longest journey made by a solo pilot in an unfuelled plane. The previous record was 76 hours, set by American pilot Steve Fossett in 2006.
