I am always working on the go.

I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.

Launching a business is essentially an adventure in problem-solving.

I've taken many knocks over the years but it has only made me stronger and more determined to succeed.

Drive, determination, passion and hard work are all free and more valuable than a pot of cash.

Well, we know that people in Australia love the idea of both Impulse and Virgin Blue getting up and adding a bit of competition, and it's fun to be able to deliver it.

One thing is certain in business, you and everyone around you will make mistakes.
