Solar plane begins record attempt

At June 3, there was a Swiss pilot called Andre Borschberg who had begun a mission to fly a plane from China to Hawaii across the Pacific ocean! The catch was the plane is one that used no fuel, but instead solar power. It was called the 'Solar Impulse 2'. The plane's Lithium-ion batteries meant that he needed to have clear skies for as long as possible before it was dark. Andre was a professional flier. He was in no doubt how tough the mission would be.
