A flight from California to New York usually takes about six hours, but for André Borschberg it's going to take a lot longer. Borschberg and fellow pilot Bertrand Piccard will leave Mountain View, California today for the Big Apple on the 'Solar Impulse,' the first solar-powered plane that can fly overnight. The goal is to make it across the US without using one drop of fuel.
Here's video of the plane soaring over San Francisco:
