The solar plane is scheduled to land early Sunday morning in New York City and complete a historic first as the only solar plane to fly across America day and night--and without fuel.
Join the Swiss-based staff of the Solar Impulse as they take your questions and explain the flight instruments, tactics and technology.
The Solar Impulse weighs as much as a sedan and flies at 40 mph on average. The plane's journey began in San Jose in March with stops in Arizona, Texas, Missouri, Ohio and Washington D.C. In each city, it has been open to public viewing, with more than 75,000 visitors viewing the plane's roughly 70-yard wingspan.
