For this thread, I just did a google search and found it, like the other videos I have linked.
I sure wish I could work on something as sexy as high tech weapons.
I don't know about the sexy part (but yeh sort of) but I can tell you that it's extremely satisfying when you get to see your efforts bear fruit against the enemies of the United States. My latest efforts have been in simulation systems for training, both operational and maintenance. In the case of my biggest effort in that regard, I got to watch the trainees actually using the system, twice in fact. In the second instance the training wasn't simulated, as the system interfaces to real sensors as well and the training is then "live" not simulated. Some of the trainees tend to get a bit excited. :)
