Solar Impulse 2 flight postponed due to weather risk

The planned flight of the sun powered plane, Solar Impulse 2, has been postponed.

The team in Nanjing, eastern China, say the weather forecasters have assessed that conditions are no longer good for the attempted flight to Hawaii.

Pilot Andre Borschberg told the BBC's John Sudworth that he was pleased not to be flying as the journey would have been too much of a risk.
