The Solar Impulse, which is the believed to be the most advanced sun-powered plane in the world, has made a landing in Phoenix in Arizona in the western US.

Developers of the experimental solar plane had announced their plans to fly the `Solar Impulse' across the US skies in May. The developers from Switzerland had listed cities that were a part of its "Across America" tour. The aircraft landed at Phoenix's Sky Harbor International Airport at 12:30 a. m. MST after it took off from Moffett Field in the Bay Area on Friday early morning.

Developers Bertrand Piccard and André Borschberg said that the tour is to showcase that the solar powered capable of flying day and night without fuel to fly across America. Solar Impulse has been designed with an aim to demonstrate the potential of solar power and not as a replacement of commercial flights.

The Solar Impulse aircraft is powered by 12,000 photovoltaic cells fitted on to its massive wings. The solar panels charge its batteries and this enables the plane to fly day and night without the need for jet fuel. The aircraft's wingspan is as wide as that of a commercial airplane but its weight is much lesser and this might make it venerable to bad weather conditions. The plane has single seating capacity and cannot fly in dense clouds.
