We had risen to probably one of the greatest challenges in history, put a man on the moon in the decade. We'd created incredible technologies. But what was most important, we'd created the teams, what I call the human factor. People who were energized by a mission. And these teams were capable of moving right on and doing anything America asked them to do in space. And what we did is we watched these teams disappear. We watched the great contractors — the Grummans, the North Americans, the Lockheeds — disappear from the horizon. I think that's really sad that as Americans we have destroyed much of this infrastructure that we had in the days when we went to the moon.
