Manned solar plane lands in dark in major US airport

The first-ever manned airplane that can fly by day or night on solar power alone landed in the dark at a major southwestern US airport, a live feed from the organizer's website showed early Saturday.

Solar Impulse, piloted by Swiss adventurer Bertrand Piccard, touched down at Phoenix's Sky Harbor International Airport at 0730 GMT after departing from California some 18 hours earlier on the first leg of cross-country journey.
