A solar-powered plane safely landed in Seville, Spain on 23 June after flying across the Atlantic. The journey took almost three days from New York and is part one of the longest legs of the first ever fuel-less flight around the world.

Solar Impulse 2 landed shortly after 7.30 am local time after a 71-hour flight that started at the John F Kennedy International Airport at about 2.30 EDT on June 20. The Atlantic flight was the 15th leg in the planes journey that is raising awareness for the use of clean energy.

One of the pilots, Betrand Piccard, said after landing: "What I deeply hope, to make this flight from New York to Seville meaningful, is that you can also be the ambassadors of this new world, this new state of mind, this new way to see the future, Because the future is clean, and it starts now,"

With a cruising speed of around 70km an hour (43 miles per hour), similar to an average car, the plane has more than 17,000 solar cells built in to wings with a span bigger than that of a Boeing 747.
