<p>Philosophy is a funny thing. You could also argue that if you are working on weapons, you are, in fact, preventing the deaths of people. Often in history, the threat of major armed conflict and loss of life has deterred different nations/organizations/groups from starting a conflict in the first place. This is obviously not always true, as we still have wars, but if you look at the Cold War just as an example, the threat of destruction kept both sides at bay and prevented a catastrophic war. Really, it would be just as easy to argue that as a “weapon designer” you are actually tasked with preventing deaths as it is to argue that you are tasked with killing people.</p>
<p>For me personally, I tend to see it as two sides of the same coin. People will always fight. People will always want power. People will always be greedy. On the one hand, having no weapons would mean that no one could get shot or stabbed or bombed or anything, but on the other hand, if no one has weapons, you know there is someone out there who will go out of their way to get weapons because of that greed. It is kind of a “damned if you do, damned if you don’t” situation, unfortunately.</p>
<p>Still, I don’t know a single aerospace engineer who does it because he/she thinks “hey lets design things to kill people!” Everyone I know does it because “hey planes are cool, and all the most cutting edge, push-the-envelope stuff goes onto military hardware.”</p>
<p>And this is all assuming that you buy into the assertion that “the vast majority of money (and hence work) is in the weapons/defense/military field” as you claim, which is simply not true. Over half of Boeing’s income comes from commercial airlines. Another sizable chunk comes from satellite and space systems. In fact, out of the roughly 157,000 people that work at Boeing, only about 68,000 of them work in what they call “defense, space and security”. If you remove the space portion of that (since no one is killed from space) you end up with far fewer than that. Just as a benchmark, Boeing Commercial Airplanes employs somewhere around 60,000 people. Northrop makes less than half of their income off of warplanes as well, and has a sizable presence in satellite and space systems and in information and communications systems. Lockheed is the only big one that gets far and away most of their income from military-oriented projects as far as I know. That doesn’t even include all the people who work places like Ball Aerospace, Cessna, Sikorsky, Bell, or any smaller, completely peaceful aircraft company.</p>
<p>Aside from the satellite and space systems going on at Boeing/Lockheed/Northrop, this hasn’t even touched on the rest of space-related careers. NASA is 100% not in the business of killing people. Their mission is to 1) run the space program and 2) develop and demonstrate technologies that other companies or groups can then use on concrete products. SpaceX, Blue Origin and Virgin Galactic are space companies and that don’t have anything to do with killing people.</p>
<p>There are many, many jobs in aerospace where your job isn’t “to help kill people.” Even the ones that you would classify as falling into that category are being done a complete disservice by your description. People do aerospace because they love planes and/or space. They do it because the idea of designing and working on a machine that can gracefully soar through the sky is exciting to them. They don’t do it because a small subset of airplanes are used militarily.</p>
<p>Using your line of logic, an electrical engineer would get stuck in a job polluting the atmosphere all day since they design things that use electricity and electricity is generated “dirtily.” Get a grip and stop crapping on peoples’ dreams just because you apparently think the whole aerospace industry is immoral.</p>
