The Solar Impulse 2 plane went through "a long night of turbulence" over the Atlantic, its weary pilot says as he continued on the challenging leg of its sun-powered trip around the world.

A plane powered entirely by the sun is flying to New York City. The Solar Impulse 2 has taken off from Lehigh Valley, 87 miles (140km) west of the "Big Apple", on a journey that should take only a few hours.

A solar-powered plane, Solar Impulse has started its second bid at a record-breaking flight across the Pacific Ocean.

Solar Impulse 2 – a solar powered aircraft – started the first round-the-world solar flight on March 9 and will fly over Bangladesh tomorrow evening if everything goes as planned
