The team says pilot Damian Hirschier performed a seven-minute flight at low altitude with the SolarStratos plane in "ideal" conditions early Friday.

The maiden flight took place at the Payerne airfield in western Switzerland where another experimental plane, Solar Impulse, performed many of its test flights before successfully circumnavigating the globe last year.

SolarStratos project head Raphael Domjan circled the globe in a solar-powered catamaran in 2012. He aims to take the 82-foot (25-meter) wide two-seater plane covered in solar panels to an altitude of over 80,000 feet (24,384 meters) by 2019.

Commercial planes fly at altitudes of between 10,000 and 60,000 feet.
