"All scientific breakthroughs start with a crazy idea and are first said to be impossible."
André Borschberg sent that tweet yesterday -- and it makes sense he would. The Swiss pilot is testing his own crazy idea: attempting to circumnavigate the world in a solar-powered aircraft.
The solar-powered Solar Impulse 2, which took off from Abu Dhabi in the United Arab Emirates in March, is circling the globe, stopping in 12 cities over five months, in an effort to bring awareness to the potential of solar energy. Currently, Borschberg is a bit more than 22 hours into the longest leg of that journey. The 120-hour solo flight will traverse the Pacific Ocean, flying from Nagoya, Japan, to Hawaii.
The Solar Impulse team is calling this leg of the journey "the moment of truth," according to the website where you can track the flight in real time, because it is the longest and riskiest part.
Borschberg and fellow Swiss pilot Bertrand Piccard, who have prepared for this solar-powered feat for a dozen years, are taking turns at the wheel of the aircraft. Takeoff for this current trip was postponed twice already on account of bad weather before the aircraft finally took off yesterday.
The one-seater futuristic aircraft has a 72-meter wingspan, roughly equivalent to a Boeing 747 passenger plane, but weighs only 2,300 kilograms, or approximately the weight of a car. Of particular importance to its ability to take multi-day trips, the Solar Impulse can fly at night.
