Solar Impulse 2 arrives in Honolulu, to land at dawn

Xinhua, July 3, 2015 Adjust font size:

Solar Impulse 2 (SI2), the first solar-powered aircraft in an attempt to fly around the world, arrived early Friday morning in Honolulu, the capital city of the U.S. state of Hawaii, and will land at dawn.

At 2:00 a.m. local time (1200 GMT), the SI2 finished the 8,200 km non-stop solo flight from Nagoya of Japan, and will land at Hawaii's Kalaeloa Airport at 6:00 a.m. local time (1600 GMT).

Flying 6,000 feet (around 2,000 meters) above Hawaii, batteries of the craft are around half of full energy that could support it for the next couple of hours, local media reported.

Hawaii is the eighth leg of the plane's 35,000-km journey around the world started from Abu Dhabi on March 9. It is piloted alternatively by Swiss explorers Andre Borschberg and Bertrand Piccard.

During the trip from Japan to Hawaii, Borschberg navigated alone for 114 hours -- 5 days and nights -- in an unheated and unpressurized cockpit, sleeping in bursts of 20 minutes while on autopilot.

Three records were set during the trip -- the longest distance of non-stop flying, the longest solo flight and the longest solar-powered flight without any fuel.

Borshberg is in a good health state, though very tired, local media said.

"Can you imagine that a solar-powered airplane without fuel can now fly longer than a jet plane," Piccard said said in a statement, "This is a clear message that clean technologies can achieve impossible goals."

The plane weighs about as much as a family sedan and has 17,000 solar cells across its wingspan.

The round-the-world trip is expected to take some 25 flight days, broken up into 12 legs at speeds between 50 and 100 km per hour. On the way to Hawaii, its average speed was around 70 km per hour.

The SI2 initially left Nanjing, the capital of east China's Jiangsu Province, on May 31 for Hawaii, but was forced to land in the central Japanese city of Nagoya due to "a wall of clouds" forming over the Pacific.

The next leg of the flight will be from Honolulu to Phoenix, Arizona, before Borschberg and Piccard fly together across the Atlantic on a return path to Abu Dhabi.

It took 12 years to build this solar plane and the first version in 2009 broke records for heights and distances travelled by a manned solar plane. Endi
