Solar Impulse 2 (Si2), a high-tech, sun-powered aircraft, is ready for the historic flight from China to Hawaii. A 62-year-old, Andre Borschberg, will attempt the 8175-kilometer, Pacific crossing flight, which will take off from Nanjing in eastern China on Thursday.

The solar aircraft resembling a dragonfly will fly over 5,070 miles of ocean expanse; the Pacific crossing will take about 120 hours. It will be the longest flight, both in distance and duration, ever made with a solar plane. This journey will take five days and a lot of courage.

Another Swiss adventurer, Bertrand Piccard aged 55, will fly a solar plane from Hawaii to Phoenix later this month. According to the official Twitter page, in order to tackle the challenges of crossing oceans, both Bertrand Piccard and Andre Boschberg have gone through a 72-hour simulation.

Borschberg and Piccard, both, hope to be the first pilots to fly a solar-powered plane around the world. After 12 long years of planning, they had launched their team expedition in March.

The Si2 had left Abu Dhabi in March and since then it has stopped in Oman, India and Myanmar. After Hawaii, this plane is slated to stop in Phoenix and New York before flying over the Atlantic Ocean.

The Solar Impulse has an enormous wingspan at 236 feet but weighs only 5,071 pounds. The plane has four solar batteries which will be recharged by 17,248 feather-light solar cells on top of the wings. The recharged batteries will then help for nighttime flying.

Borschberg, CEO, co-founder and pilot of the Si2 said that he plans to take 20 minutes of rest for eight times each day if weather permits him to do so.

The solar wonder will create a breakthrough in energy efficiency and modern technology, when a Boeing 747 takes about 36,000 gallons of fuel to fly from eastern China to Hawaii!
