The so-called, uh--astronaut would merely be a redundant component, ja? http://www.angelfire.com/movies/clos...ghtstuff-s.txt -- Process shall set you free from the need for rational thought. these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |

I wouldn't worry about the vacuum tubes as I would the big electrical pulses coming down the electrical cables hooking all the equipment together as it acted like an antenna. At least on the Minuteman silos, they were concerned about phone lines enough that they installed EMP arrestors that relied on neon tubes to shut things down a lot faster than standard lightning arrestors could. A friend of mine has one of these surplus EMP arrestor phone panels installed in his house that he got when they were shutting a silo down under SALT. Still use those gas discharge tubes where MOVs aren't hefty enough or long-lived enough. They can absorb a pretty good jolt, repeatedly. --Damon |
