Solar plane lands in Phoenix on first leg of US journey

The plane, dubbed the Solar Impulse, took off from San Francisco Bay around 20 hours earlier. The owners of the plane, that has the same wingspan as an Airbus A340 but it weighs just 1.6 tonnes, hope to finish the voyage in New York. via Pocket http://www.bbc.co.uk/news/science-environment-22414444#sa-ns_mchannel=rss&ns_source=PublicRSS20-sa
