"'We can't fly into clouds because it was not designed for that,' Borschberg said as he piloted the lumbering plane with its 63-meter (207-foot) wingspan toward the eastern French city of Lyon at a cruising speed of just 70 kilometers an hour (43.5 mph)."
After a 20-hour flight, the plane will land in Madrid, change pilots and continue on to the Moroccan capital of Rabat. [Read More]
