The solar-powered aeroplane Solar Impulse has landed in Silicon Valley, California, after a three-day flight over the Pacific Ocean from Hawaii.
High winds delayed the landing at Moffett Airfield, Mountain View, as pilot Bertrand Piccard flew in a holding pattern off the coast.
“The Pacific is done,” he declared just before landing.
The latest leg of the round-the-world flight was the riskiest yet because of the lack of emergency landing sites.
“You know there was a moment in the night, I was watching the reflection of the moon on the ocean and I was thinking, ‘I’m completely alone in this tiny cockpit and I feel completely confident’,” Mr Piccard told reporters afterwards.
“And I was really thankful to life for bringing me this experience; it’s maybe one of the most fantastic experiences of life I’ve had.”
It was Mr Borschberg who flew into Kalaeloa last July and he will take the controls on the next leg across the US mainland.
The two Swiss pilots’ intention is to reach New York by the start of June, to begin preparations for an Atlantic crossing.
Assuming this is completed successfully, it should then be a relatively straightforward run back to the “finish line” in Abu Dhabi.
Mr Piccard and Mr Borschberg have been working on the Solar Impulse project for more than a decade.
