Solar Impulse 2 has broken a distance record for solar-powered planes as part of its bid to be the first to circumnavigate the globe powered solely by the sun.
By the time it arrived in Ahmedabad, in western India on Tuesday, the plane had flown 1468 kilometres, the flight’s organisers said on Wednesday.
Solar Impulse project chairman and co-pilot Bertrand Piccard was at the controls.
The plane’s backers say it was the longest point-to-point distance flown by a solar-powered plane, but the record must be confirmed by air sports governing body Federation Aeronautique International.
Solar Impulse’s CEO and co-founder Andre Borschberg set the previous record in Solar Impulse 1 when he flew 1386 kilometres across the United States.
The aircraft touched down Tuesday in the western state of Gujarat after a trip from the Omani capital Muscat in little less than 16 hours.
In longest single leg of the planned circumnavigation, one of the pilots will fly solo non-stop for five days and nights across the Pacific from Nanjing, China to Hawaii, a distance of 8500 kilometres – again smashing the record.
Solar Impulse 2 is powered by more than 17,000 solar cells built into wings that, at 72 metres, are longer than those of a Boeing 747 and approaching those of an Airbus A380 superjumbo.
In total, the plane is to travel 35,000 kilometres and will cross two oceans.
The circumnavigation, which is to take place in 12 steps, requires 25 days worth of flight time spread over five months.
The team hope to promote green energy with their round-the-world attempt, which was ridiculed by the aviation industry when it was first unveiled.
