Two Swiss pilots are expected to embark on Monday morning on the first attempt to fly around the world in a plane propelled only by the sun.
Bertrand Piccard and André Borschberg will take turns piloting the single seater Solar Impulse 2 for 21,747 miles (35,000km) over 12 legs, including gruelling five- to six-day stints across the Atlantic and Pacific oceans. The entire journey will take five months.
