After 10 days in St. Louis, the first plane that can fly day or night without fuel is on its way to Cincinnati.
Solar Impulse started its cross-country trip in Northern California on May 3. It arrived in St. Louis on June 4. The plane took off from Lambert Airport early Friday.
After a stop in Cincinnati it will continue on to Washington before eventually ending the journey in New York. The plane flies at a speed of about 40 mph and carries only the pilot.
