Irreverence ran on both sides of our family...my parents brought me up to think we could all change the world.

And in the process, we have come up with fuels - algae-based fuels, isobutanol-based fuels and other fuels - that we think will power the planes in the future so that, you know, by 2020 I hope that our planes will be powered on fuels that are clean fuels and are not polluting the environment so that we'll have a green airline and an airline that actually has fuels that will be hopefully cheaper than the dirty fuels of the past. So [we're] doing good and also turning a profit at the same time.

I was trouble - and always in trouble. Aged eight I still couldn't read. In fact, I was dyslexic and short-sighted. Despite sitting at the front of the class, I couldn't read the blackboard.

I think that not relying too heavily on one bank and one bank manager is a good rule to learn.
