A solar plane attempting to fly around the world without a drop of fuel plans to make an unscheduled stop in Nagoya, Japan, because of bad weather.
Swiss pilot André Borschberg took off from Nanjing, China, on Sunday on what was to be the longest leg of the journey, an 8,175-kilometer (5,079-mile) flight to Hawaii.
Instead, the Solar Impulse 2 will land in Nagoya, Japan, according to the website and Twitter feed for the plane.
Japanese Transport Ministry and Nagoya airport officials confirmed that they are making arrangements for an unanticipated landing at one of two airports.
The journey started in March in Abu Dhabi, and the plane has stopped in Oman, India, Myanmar and China. The flight from Nanjing to Hawaii is the seventh of 12 flights and the riskiest.
