André Borschberg — the pilot who broke the record for longest unrefueled solo flight — recalled the experience of flying the Si2 over the Pacific and discussed the future of Solar Impulse during his keynote speech at the Polyurethanes Technical Conference in Orlando, Florida, on Monday. On the horizon: a wrap on the round-the-world trip of the Si2, an unmanned version of the aircraft and a possible collaboration with Google.

 

The Si2, which Borschberg flew from Japan to Hawaii, is the only manned solar aircraft that can fly day and night without fuel.
