It's historic achievement for the electric aircraft, powered solely by sun, a journey that covered some 40,000 km.

Via Solar Impulse 2:

"We have now just watched our shared dream unveil, becoming a reality. It’s with great emotion that I write this last blog to report on the Round-the-World solar flights. Emotions, tears, relief, exhilaration is what we are all feeling right now after completing the first Round-the-World solar flight in history."

One of the highlights on the trip was a record of 118 hours or nearly 5 days and nights non-stop flight (about 5,000 miles / 8,000 km) between Japan to Hawaii.  Of course, not all went as planned, as battery damage then grounded the Solar Impulse 2 in Hawaii for months.

About three months ago, the Solar Impulse 2 was fully repaired and cleared for flight, resuming the journey by arriving in California and then to New York...so it wasn't the "quickest" round-the-world flight to be sure.

Quick specs:

  • wingspan of 72 m
  • 17,248 photovoltaic cells (enough to fly at daytime and accumulate energy for the whole night, it could theoretically stay in the air forever)
  • weights 2,300 kg (5,070 lbs), including 633 kg is battery pack
  • four motors each of 17.5 HP or about 13 kW for total 50 kW output
  • top speed of up to 90 km/h (56 mph)
