The Solar Impulse solar plane, which in 2010 demonstrated it could harvest enough energy by day to stay aloft all night, will soon take its first international flight. The team will be headed by Bertrand Piccard, the man who piloted the first non-stop round-the-world balloon flight, and will leave from Brussels on May 2nd.
The Solar Impulse team needs the permission of authorities to pilot its plane, which has the wingspan of a Boeing 777, through international air traffic networks. After the flight attempt, the Impulse is expected to be shown at the International Paris Air Show in June.
