ABC News

The Solar Impulse solar-powered airplane made history in 2010 when it embarked on the first-ever solar-powered night flight, and again in 2012 when it made the first intercontinental solar-powered flight (Europe to North Africa).

Now the co-founders and pilots of Solar Impulse have announced plans to conduct the first solar-powered coast-to-coast United States flight – Solar Impulse Across America – kicking off early next month.
