The solar powered plane Solar Impulse 2 took off from Nagoya Airfield in Japan on Monday for a trans-Pacific crossing as a part of an unprecedented bid to circle the planet without fuel.
“This is a one-way ticket to Hawaii,” Solar Impulse said on its website.
“Andre Borschberg [pilot] has passed the point of no return and must now see this 5 days 5 nights flight through to the end.”
The Solar powered plane, which carries 17,000 solar cells on its wings, left Nanjing in China on May 31, but was forced to land in Nagoya due to bad weather.
The plane started its 35,000-kilometre journey by taking off from Abu Dhabi in March.
It is expected to land in Hawaii in 120 hours.
