A solar-powered plane, without a drop of fuel, was about to embark on a very long journey from China to Hawaii on Sunday. Unfortunately, the captain of the plane was forced to make an emergency landing in Nagoya, Japan because of bad weather and will have to wait out until the weather improves, according to San Francisco Gate.

Swiss pilot André Borschberg had the plane fly from Nanjing, China on Sunday for a six-day 8,175 km (about 5,077 miles) flight to Hawaii, the longest leg of the journey.

"It's just the weather doesn't fit. Everything we could do has been done and was successful. What we cannot control is the weather. So we land in Nagoya, we wait for better conditions, and we continue," Bertrand Piccard, the co-pilot, initiator and chairman of Solar Impulse 2, told Solar Impulse TV, the live feed of the organizer.

The long journey began back in March and the solar-powered plane has made stops in Oman, India, Myanmar and China.

The latest flight is the seventh and by far the riskiest since there is no place to land in between, requiring the pilot to wait for a few more days until better weather arises, according to the Associated Press.
