First Solar Impulse prototype HB-SIA over San Francisco
DLR already supported the construction of the first Solar Impulse prototype, HB-SIA, in 2008 and 2010 during its development stage, performing component tests and a stationary vibration test. In 2010, the Solar Impulse solar aeroplane succeeded in, for the first time ever, flying non-stop for one whole day and night. In 2013, the first Solar Impulse prototype flew across the United States of America. Here, a view of the solar-powered aircraft as it flies over San Francisco.
