To be blunt: you wind up working on things that are explicitly designed to kill other human beings. That is what you are saying. That's the elephant. Many here would find such a thing immoral and unethical. I know that. I have my own personal reasons for doing what I do. They make sense for my own life. So fnordfnordfnord already linked to a comment where I mention working on sounding rockets (in addition to the aircraft/telemetry) Those are for purely scientific research. I've done the peaeceful engineering thing, I guess. And the program does some good science! But if you look at my comment history more, I have some comments where I talk about working in a really bad environment. Guess what? Same place, the sounding rocket program. So I left and changed jobs. To be honest, I try not to worry about all of this so much, mainly because I'm actually happy to go to work now. I am, however, usually happy to discuss this seeming contradiction of trying to be a moral/ethical person while working in aerospace... Just because I don't think about it every day doesn't mean I haven't examined and reflected upon it.
