In my little world, "nuke" is just a word to describe what happens to my leftover when I put them into the microwave. But when I was doing a week of outreach on an Air Force base, nuke meant something far more lethal - as in nuclear missile. This particular base was home to scores of the missiles that have been part of the front lines of our nation's defense for years. They're kept in underground silos, surrounded by very high-tech security systems. It was my privilege to be taken on a visit of one of the launch control centers there, each one of these command centers is responsible for ten missiles. At the time I was there, the center was manned by two airmen who were on 24-hour shifts called "alerts." When they were on "alert," they went underground into a fully self-sustaining unit that contains both the launch systems and the systems that protect those missiles from intruders. They showed me the systems which monitor virtually every movement every minute for their ten missiles sites. In fact these protection systems are so finely tuned that a plastic bag blowing across the prairie can trigger it, or some rabbit who has no idea what is under his little feet. Frankly, I was encouraged that we have crews like this that are on full alert - what they're responsible for needs full alert!
