For example, in graduate school we worked on security-related software. My advisor's group is continuing in that field and recently took over a famous, malicious botnet!
I also learned something new this week. I didn't know that the Saturn V main engines (which burned kerosene (RP-1) and LOX) were actually started with hypergolics. Reminds me of using starting fluid (ether) on an old lawn mower. On second though, probably not a good comparison :)

The video also shows the amazing amount of water dumped on the launcher to suppress sound.
There's also video around from those days showing staging. I think this one is in real-time, and this one slowed.
Next thing you know, we'll be talking about ullage motors.
