The Solar Impulse plane HB-SIA set a new distance record for solar-powered flight on the second leg of its trans-American journey on 22 May 2013. The craft landed in Dallas, Texas, after an 18-hour flight and a journey of 1541 km from Phoenix to Arizona.
In the coming weeks, the craft will make a stop-over at St Louis, Missouri, and Washington DC before heading to New York in early July. The objective of this project named as Across America is to showcase the capabilities of renewable energy. The Across America is termed as the first cross-continental, solar powered flight.
The Solar Impulse HB-SIA has the same wingspan as an Airbus A340. The plane's wing and stabiliser are covered with approximately 12000 solar cells, which drive its four propellers and charge the plane's 400kg of lithium-ion batteries for night-time flying.
