I'm not sure what you are implying. The nature of the work described above was to prevent a disaster like the shooting down of commercial Flight 655 from ever happening again.
Yes precisely, and (to GP) that's software and UX design. Not comparing with, it's that exact thing (in that case)
Nothing personal, just interesting to see how engineers think about how their work can harm other humans, yet some jobs are about creating machines or weapons meant for destruction.
In my previous job writing a naval combat system (not Aegis) I figured that I couldn't prevent warships from existing, but I could make the combat system better, safer, easier and less error-prone to use which would ultimately reduce the likelihood of people being killed inadvertently. But I totally respect people who choose not to work in defence.
