SOLAR Impulse 2, an entirely solar-powered plane, left from Sevilla to Cairo for the penultimate leg of its circumnavigational voyage.
The one-seat vessel has the wingspan of a Boeing 747 and the weight of an automobile.
The Solar Impulse began circumnavigating globe last March. After Cairo, the plane heads for Abu Dhabi to complete the globular odyssey.
On its trip, the revolutionary aircraft broke the record for the longest uninterrupted flight in history on its 118-hour journey from Japan to Hawaii.
