Solar Impulse, the fuel-free aeroplane, has completed the fifth leg of its round-the-world flight.
The vehicle, with Bertrand Piccard at the controls, touched down in Chongqing in China just after 17:30 GMT.
It had left Mandalay in Myanmar (Burma) some 20 hours previously.
The intention had been to make the briefest of stops in Chongqing before pushing on to Nanjing in the east of the country, but that strategy has been abandoned because of weather concerns.
The team will now lay over in southwest China until a good window opens up on the east coast.
"May be we have to wait a few days. We'll have a first image from the meteorologists [on Tuesday]," said mission director Raymond Clerc.
Getting to the city of Nanjing would set up Solar Impulse to make its first big ocean crossing - a five-day, five-night flight to Hawaii.
Leg five proved to be a tough one for Bertrand Piccard.
He covered a distance of 1,459km in a 20-hour, 29-minute flight from Mandalay, and faced some strong winds as he approached Chongqing Jiangbei International Airport.
The wheels of Solar Impulse were timed to touch the runway at 01:35 local time, Tuesday (17:35 GMT, Monday).
The team will use the time in Chongqing to promote renewable energy as part of its "future is clean" campaign.
