Payerne: A sun-powered plane made a successful test flight on Monday, clearing a vital hurdle towards its goal of a round-the-world trip next year, its pilot and mission chiefs said.
Solar Impulse 2 carried out a flight lasting two hours and 15 minutes, half an hour longer than scheduled, German test pilot Markus Scherdel said.
"Everything worked as expected," Scherdel told a press conference at an air base in Payerne, central Switzerland.
"Of course, we have to do more testing, but it's a good start and I'm looking forward to flying the airplane the next time."
Built from carbon fibre, the 2.3-tonne plane has four 17.5-horsepower electrical motors powered by 17,248 solar cells studding its fuselage and 72-metre (234-feet) wingspan - as long as that of an Airbus A380.
It is the successor of Solar Impulse, a record-breaking craft that in 2010 notched up a 26-hour flight, proving its ability to store enough power in lithium batteries during the day to keep flying at night.
