Solar plane lands in Arizona on journey across U.S.
Single-seater Solar Impulse completes 1st leg of trip across country
A solar-powered airplane landed in Phoenix early Saturday morning after a 19-hour flight from California on the first leg of an attempt to fly across the United States with no fuel but the sun's energy.
The European-designed Solar Impulse set down about 12:30 a.m. local time at Sky Harbor Airport after flying several hours after sundown on a journey pilot Bertrand Piccard described as a "milestone" in aviation history.
The Solar Impulse — considered the world's most-advanced sun-powered plane — left Moffett Field in Mountain View near San Francisco just after dawn Friday.
Its creators said the trip is the first attempt by a solar airplane capable of flying day and night without fuel to fly across America.
Video posted on the expedition's website showed a smiling Piccard shortly after landing, as he waved to well-wishers and held up a flag emblazoned with the Solar Impulse name.
"It's a little bit like being in a dream," Piccard said as he stepped on the tarmac.
From Phoenix, the aircraft will travel to Dallas-Fort Worth airport in Texas, Lambert-St. Louis airport, Dulles airport in the Washington area and New York's John F. Kennedy airport. Each flight leg will take about 19 to 25 hours, with 10-day stops in each city.
"All the big pioneers of the 20th century have tried to fly coast to coast across America," Piccard, one of the plane's founders, said before the flight. "So now today we're trying to do this, but on solar power with no fuel with the first airplane that is able to fly day and night just on solar power."
The plane is powered by about 12,000 photovoltaic cells that cover massive wings and charge its batteries.
The delicate, single-seat Solar Impulse flies around 64 km/h and weighs about as much as a car, making it vulnerable to bad weather.
Its creators said solar planes will never replace fuel-powered commercial flights. But the goal is to showcase the potential of solar power.
"What we look for is to have a new milestone in this very exciting history of aviation that can attract interest of the people, of the political world, of the media and show that with renewable energies and clean technology for energy efficiency, we can achieve impossible things," Piccard said.
