Solar plane pilot: 'I wouldn't leave if I had doubts'

Swiss pilot Andre Borschberg has said that he has no doubts about his bid to cross the Pacific, from China to Hawaii, in the zero-fuel Solar Impulse aeroplane.

The experimental aircraft, which has a wingspan bigger than a jumbo but weighs little more than a large car, left Nanjing at 02:39 (18:39 GMT).

It is estimated that it will take Mr Borschberg five to six days of continuous flight to reach his destination.
