Solar plane makes first flight

A solar-powered plane, that will try to fly around the world next year, has made its first test flight.

Solar Impulse 2 lifted off from Switzerland early this morning and returned two hours later.

The carbon-fibre aircraft has a huge wingspan of 72m - that's wider than a Boeing 747 jet - but it weighs about the same as a large car.

The plane is a larger, improved version of the aircraft that flew across America last year.
