It took off from Cairo on its last leg at an opportune time Sunday, having beforehand crossed Asia, North America, Europe, and North Africa.
Borschberg, 63, crushed the record for the longest continuous voyage in flying history with the 8,924-kilometer (5,500-mile) flight between Nagoya, Japan and Hawaii that endured 118 hours.
No heavier than an auto however with the wingspan of a Boeing 747, the four-motor battery-fueled flying machine depends on around 17,000 sun oriented cells inserted in its wings.
