Solar Impulse 2 plane will circumnavigate Earth in 2015
Last year, Bertrand Piccard and André Borschberg became the first pilots to fly across America in a featherweight plane fueled only by the sun. The Swiss duo now plans to circumnavigate the world in a next-generation solar aircraft named the Solar Impulse 2. The March 2015 flight will start and finish in Abu Dhabi.
