CAIRO—Flying low over haze-covered Pyramids in Giza, an experimental solar-powered airplane arrived on July 13 in Egypt as part of its globe-circling voyage.
The aircraft, Solar Impulse 2, flew out of the Seville airport in Spain on Monday and landed at the Cairo International Airport on Wednesday morning. This leg of the trip had been expected to last about 50 hours and 30 minutes.
The flight, piloted by Swiss man Andre Borschberg, had arrived in Seville on June 23 after an unprecedented three-day flight across the Atlantic.
The around-the-world voyage began in March 2015 in Abu Dhabi in the United Arab Emirates and is due to finish there, too, sometime next week or later.
The wings of Solar Impulse 2, which stretch wider than those of a Boeing 747, are equipped with 17,000 solar cells that power propellers and charge batteries. The plane runs on stored energy at night.
Ideal flight speed is about 45.06 kph (28 mph), although that can double during the day when the sun’s rays are strongest.
The solar project, which is estimated to cost more than $100 million, began in 2002 to highlight the importance of renewable energy and the spirit of innovation.
