An engineer is a person who is attempting to do something useful with the knowledge of science. The point is that Apollo, indeed the entire space program, is the work of engineers. Engineers often serve science by creating the instruments that scientists need, but it's still engineering, not science. If you live in an industrialized society, nearly everything you do required an engineer somewhere. The clothes you wear were made in a factory by complex machines which were designed by an engineer.
Engineers matter .
And I think that down deep people know it. I don't get negative reactions from people such as the one I got from that guy in the bar very often. Mostly people are respectful. One of the privileges given to some of us is to do something for the very first time, to experience something no human has ever experienced before. But when engineers do something new, it changes all our lives.
