The solar-powered plane has landed in the US capital, Washington, in the penultimate leg of a transcontinental trip to New York City. The project's creators want to demonstrate the potential of solar power.
The solar-powered plane has landed in the US capital, Washington, in the penultimate leg of a transcontinental trip to New York City. The project's creators want to demonstrate the potential of solar power.
The
single-seat Solar Impulse plane touched down in Dulles International Airport on
Sunday, after making an unplanned stop in the Midwestern city of Cincinnati
because of difficult weather conditions.
The trip
from Cincinnati to Washington took 14 hours. Solar Impulse runs on four
electric propellers powered by 12,000 solar cells mounted on its 63-meter
(68-yard) wingspan. At night, the plane reaches an altitude of 27,000 feet and
then glides downwards, using virtually no energy until the sun rises again.
Solar Impulse travels at a speed of approximately 64 kilometers per hour (40
miles per hour).
Solar
Impulse will be on display in Washington for two weeks, at the Udvar-Hazy wing
of the Smithsonian Air and Space Museum.
"To be
hosted by the Smithsonian Institution is an honor for Solar Impulse," said
Bertrand Piccard, who is swapping the piloting duties with his fellow Swiss
national Andre Borschberg.

Although
Solar Impulse had originally planned to fly directly from St. Louis, Missouri,
to Washington, poor weather conditions meant that Piccard would have had to
pilot the plane for longer than the 24-hour set limit. Instead, an unscheduled
stop was made in Cincinnati.
The first
leg of Solar Impulse's transcontinental journey took place on May 3, from San
Francisco, California, to Phoenix, Arizona. Solar Impulse is expected to
complete its US trip and land in New York City in July.
Piccard and
Borschberg are using their US trip as preparation for their ultimate goal, a
flight around the world in 2015.
