We had an airplane, a Beechcraft Baron, that we - I had since 1981. And Annie [Glenn] and I both of had to have knee replacements unfortunately over the past year, and it made it more difficult to climb up on the airplane. We weren't using it that much so we did - it hurt a lot but I finally sold the airplane.
John GlennI think sometime we will go to Mars and I think we'll explore it with humans sometime, but I think it's really wise to do all the robotic exploration ahead of time and learn as much as possible. Once we have learned as much as possible with the robots, then that's the time to send people, and let them then continue the research that the robots have started.
John GlennExploration, of course, is going to new places, but I don't think we go to new places just solely to say: "Well, we've been there," and come back, interesting though it may be. To me, each time we go farther into space we should use that to do basic research - basic research that can't be done before you go there.
