PAYERNE: Just months after two Swiss pilots completed a historic round-the-world trip in a Sun-powered plane, another Swiss adventurer on Wednesday unveiled a solar plane aimed at reaching the stratosphere.

The SolarStratos, a sleek, white two-seater aircraft with long wings covered with 237 square feet of solar panels, is set to become the first manned solar plane to make a stratospheric flight, according to Raphael Domjan, who is behind the project.

`Our goal is to demonstrate that current technology offers us the possibility to achieve above and beyond what fossil fuels offer,` he said in a statement, after unveiling the plane at the Payerne airbase in western Switzerland.

SolarStratos is scheduled to begin test flights next February, while medium altitude flights are planned for next summer, and the first stratospheric flights should take place in 2018, the statement said.

The statement also claimed the craft could `reach space.` `Travelling to the stratosphere will take approximately five hours: 2.5 hours to reach space, 15 minutes of broad daylight and stars, then three hours to return to Eadh,` it said.

The stratosphere lies above Eadh`s lowest atmospheric layer, called the troposphere. At middle latitudes, the stratosphere runs from a lower boundary of about 10,000 metres to an upper boundary of about 50,000 metres.-AFP
