The sun-powered Solar Impulse 2 aircraft completed its historic flight without consuming a drop of fuel, touching down successfully in Hawaii.
The 4,000-mile leg from Nagoya, Japan, to Hawaii was not only the world's longest solar-powered flight both by time and distance, it also set the record for longest solo flight by time.
The propeller-driven plane was originally scheduled to fly directly from Nanjing in China to Hawaii. But bad weather along the way forced a diversion to Japan that extended for almost the whole of June as forecasters waited for better conditions.

Piloted by veteran Swiss aviator Andre Borschberg, the plane took five days to make the historic voyage from Japan to Hawaii and landed on Friday shortly after dawn at Kalaeloa Airport on the main Hawaiian island of Oahu.
What is Solar Impulse 2?
The Solar Impulse 2 set off from Abu Dhabi earlier this year in a multi-leg attempt to fly around the world without a single drop of fuel.

It has 17,000 solar cells and on-board rechargeable batteries with a top speed of 140 kilometres an hour.

Its wingspan is longer than that of a jumbo jet but the carbon-fibre aircraft weighs only 2.3 tonnes(2,300kg) a little less than a Mahindra Scorpio.

The plane is the successor to Solar Impulse, which managed a 26-hour flight in 2010, proving its ability to store enough power in lithium batteries during the day to keep flying at night.

Ridiculed by the aviation industry when it was first unveiled, the venture has since been hailed around the world, including by the UN chief Ban Ki-moon.
