An aircraft attempting to circumnavigate the globe powered only by the sun's energy has broken a world record for the longest non-stop solo flight, the project team said.
The Solar Impulse 2, which took off from Japan on Monday on the seventh leg of its journey, has shattered the solo-flight record threshold of 76 hours while crossing the Pacific.
The plane, which has a wingspan bigger than a jumbo jet, is expected to land in Hawaii around 14:30 GMT on Friday.
Solar Impulse 2, piloted alternatively by Swiss explorers Andre Borschberg and Bertrand Piccard, set off on its 35,000km journey around the world from Abu Dhabi on March 9.
