Why don't you fix your little problem and light this candle?

Obviously I was challenged by becoming a Naval aviator, by landing aboard aircraft carriers and so on.

The same way people are now paying a couple thousand dollars to fly to other parts of the world, people will be paying $50,000 to spend a weekend on a space station.

I think first of all you have to be there for the right reason.

We wanted to be in great shape, we wanted to be able to cope with zero gravity, we wanted to be able to cope with accelerations and decelerations and so on. So all of us trained so that we were probably in the best physical condition we had ever been in up until that point.

We need a continuing presence in space.

It's a very sobering feeling to be up in space and realize that one's safety factor was determined by the lowest bidder on a government contract.
