Solar Impulse, a solar-powered airplane made with plastic and composite components, is to fly to New York from Dulles airport in Virginia for the fifth and final leg of its Across America flights on July 6.
The journey across the country began May 3 in San Francisco, as part of a drive to promote energy efficiency and clean technologies, the Solar Impulse team said in news release.
The final leg marks the "historic achievement" of the US coast-to-coast flights, made with an airplane capable of flying day and night without fuel, powered exclusively by solar energy.
The 64-meter wingspan plane, which has a cockpit made of rigid polyurethane foam, uses materials such as carbon nanotubes and PU foam.
