designers are working on the 2nd aircraft!
The second Solar Impulse ,HB-SIB , will be build with a pressurized cockpit and advanced avionics to allow for transcontinental and trans-oceanic flights.
The cockpit will include cabin pressurization, supplemental oxygen and various environmental support to the pilot to allow a cruise altitude of 12,000 metres (39,000 ft).
The flight would circle the world in the northern hemisphere near the equator.
A two-seater is envisaged depending of the improved battery efficiency to reduce the weight .
When ?...........Suchs as the first international flight to Brussels,let guess heu..... 13 may 2013 ...............???
