Solar Impulse 2 prepares to fly

Solar Impulse 2 (photo above by is a solar-powered aircraft with a wingspan of 71.9 metres, which will begin a planned around-the-world flight in late February or early March, starting from Abu Dhabi, where the Abu Dhabi Solar Challenge was recently held (and where the aircraft has recently arrived). The video below shows the aircraft’s maiden flight. It will be interesting to see how this goes!
