The Solar Impulse technical flights have begun! There will be at least 4 of them over the coming weeks. These flights are designed to check the aircraft’s maneuverability and responsiveness in preparation for this spring’s Across America mission – which will kick off starting May 1st. They are necessary to ensure proper functioning and overall safety of HB-SIA which has undergone fulldisassembly and reassembly in March for transport from Switzerland to the United States.
