A trip to space is a big motivator to give up some things in your personal life. Obviously, you can't give up everything and you don't want to.
There's been a lot of discussion about NASA culture and changing that. I think our culture has always been one of trying to do a very difficult job and do it well.
Later, after flying in the Navy for four or five years, spending some time on an aircraft carrier, I applied to and was accepted in a program where I went to graduate school first and then to the Naval Test Pilots School.
After the loss of Columbia a couple of years ago, I think we were reminded of the risk. All of us, though, have always known that the Space Shuttle is a very risky vehicle, much more risky than even flying airplanes in combat.
I personally believe this Agency has always been very dedicated and has always worked as hard as it possibly can to do things as safely and as effectively as possible.
It's important to bring things back from the Space Station because, unlike somebody living at the house where the garbage truck comes by twice a week, they don't have that in space.
There are a lot of dedicated people out there that don't get the recognition that we get, but they're as important as the people that are sitting in the vehicle.
I think we've done that. But it's not something you really notice, 'cause I've always thought the people here have always done their best, and they continue to do their best. They just might do it a little bit differently.
Having the benefit to our society, not only here in the United States but throughout the world with the amount of invention you get from having a space program, is well worth the risk that an individual like myself has to take by flying in the vehicle.
I think I was very interested in the space program as a kid, watching the first Apollo missions to the moon, and it's something I thought that would be a lot of, of fun and exciting and a very worthwhile job.
