Liftoff is very, very gentle, contrary to what most people think. Because you remember, the weight of the booster - the amount of thrust on the engine is just barely enough to get the booster underway. And so it's a very gentle liftoff, contrary to what most people think when they see all the fire and smoke of launch.
John GlennAs far as actually setting up colonies of people who would live their whole lives in space, I think we're a long ways from doing that yet, and I think we have many, many decades before we could be able to even consider something like that.
John GlennI don't like the way the whole thing has developed. And I just hope that we develop our own transportation system, both spacecraft and new boosters, as soon as possible. I hate to think that we may be out there seven to ten years out and dependent on the Russians for our journey into space.
