Washington: The single seater Solar Impulse plane, attempting a record-breaking trip across the US, made a smooth landing here today, leaving it with just one more hop to go in its cross-continent journey.
The Swiss-made 63-meter-wide aircraft set down at Dulles International Airport at O4:15 GMT, with Solar Impulse chairman Bertrand Piccard at the controls.
The trip from Cincinnati Lunken Municipal Airport took more than 10 hours, an hour and a half longer than it would have taken to drive.
Solar Impulse is designed to demonstrate how solar power alone can take a plane across the country, and eventually around the world, `NBC News` reported.
Although this trip didn`t set any speed records, it did include a first-ever overnight "pit stop."
"For the first time, the solar airplane was able to enjoy a starry night under the watchful eyes of its bodyguard, the ground crew," the Solar Impulse team said.
Yesterday`s departure was delayed more than two hours due to fog at the Cincinnati airport. The condensation on Solar Impulse`s wings, which double as solar arrays, were laboriously wiped off by the crew before the plane`s takeoff.
Solar Impulse`s "Across America" adventure is aimed at highlighting the plane`s technologies and preparing the way for an even more ambitious round-the-world odyssey in 2015.
The carbon-composite plane has the wingspan of a Boeing 747 jet but is as light as a passenger car. The plane`s power is generated by the 12,000 solar cells mounted on the wings and horizontal stabiliser, the report said.
According to Piccard, the Solar Impulse`s technologies could go commercial within the next five years.
The plane`s American voyage officially began on May 3 with Solar Impulse`s takeoff from Moffett Field in California, and continued with several stopovers.
The journey is expected to end with a Washington-to-New York flight in early July.
