Solar Impulse Airplane To Launch First Sun-Powered Flight Across America

First time accepted submitter markboyer writes "The Solar Impulse just landed at Moffett Field in Mountain View, California to announce a journey that will take it from San Francisco to New York without using a single drop of fuel. The 'Across America' tour will kick off this May when founders Bertrand Piccard and André Borschberg take off from San Francisco. From there the plane will visit four cities across the states before landing in New York."
