A solar plane attempting to fly around the world without a drop of fuel plans to make an unscheduled stop Monday night 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, a five-day, 8,175-kilometer (5,079-mile) flight to Hawaii.
Instead, the Solar Impulse 2 will land in Nagoya in central 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 Nagoya Airport in central Japan.
Elke Neumann, a spokeswoman for the Solar Impulse project, said from Nanjing that the teams had noticed the bad weather pattern about 36 hours ago.
"We thought we might go through it," she said. "But between Japan and Hawaii there's no place to stop ... so we said, for us, the pilot's safety and the plane's safety are really a priority right now. So we said, let's wait the weather out a bit in Japan."
The plane is to land sometime after 10 p.m., after scheduled flights at the airport end.
