World News: Solar plane’s first transcontinental flight delayed by clouds - thestar.com

Fog on the runaway at its home base in Payerne, Switzerland, delayed the take off by two hours, demonstrating how susceptible the prototype single-seater aircraft is to adverse weather.

“We can’t fly into clouds because it was not designed for that,” Borschberg said as he piloted the lumbering plane with its 63-metre wingspan toward the eastern French city of Lyon at a cruising speed of just 70 kilometres an hour.
