Pioneering Swiss solar-powered aircraft Solar Impulse landed in Brussels on Friday after completing its first international flight, 13 hours after it took off from Switzerland.
The single-seater had lifted off gently in clear blue skies from Payerne airbase at 8:40 am (0640 GMT) after being delayed by early morning mist.
It covered the roughly 480 kilometres (300 miles) from western Switzerland to Brussels airport, flying over France and Luxembourg at 3,600 metres (11,880 feet).
Solar Impulse HB-SIA, which has the wingspan of a large airliner but weighs no more than a saloon car, made history in July 2010 as the first manned plane to fly around the clock and through the night on the sun's energy.
It holds the endurance and altitude records for a manned solar-powered aeroplane after staying aloft for 26 hours, 10 minutes and 19 seconds above Switzerland, flying at 9,235 metres (30,298 feet).
The high-tech plane has since flown several times, notably between Geneva and Zurich airports, but the journey to a busy airport in Brussels through crowded airspace was regarded as a new test.
HB-SIA relies on 12,000 solar cells on its 64-metre (200-foot) wings to charge the batteries that provide the energy for the 10-horsepower electric motors driving four propellers.
Its record-breaking flight last year demonstrated its capacity to store up enough energy to fly through a summer night.
The showcase for green technology will be on display at Brussels airport until May 29 before flying to the international air show at Le Bourget in Paris from June 20 to 26.
The Solar Impulse team is planning to fly even further, including possible transamerican, transatlantic and round-the-world flights -- in stages -- in 2013 and 2014 using a slightly larger aircraft.
