Chat with the crew of the solar plane as it completes its journey across America

The solar plane is scheduled to land in New York City this weekend and complete a historic first as the only solar plane to fly across America without fuel day and night.

On Saturday at 12:30 p.m. ET, join the Switzerland-based staff of the Solar Impulse as they take your questions and explain the flight instruments, tactics and technology. The plane is scheduled to land at Kennedy airport in New York City after midnight Sunday.

The Solar Impulse weighs as much as a sedan and flies about 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. The plane has been open to public viewing at each stop, and more than 75,000 visitors have viewed the plane's roughly 70-yard wingspan.
