Mijo, I am rather surprised at your attitude toward isolating "electronics". Perhaps you eschew the use of tube equipment as absolutely as you prefer spring suspended turntables, but anyone who does use tube equipment will know full well that tubes are sensitive to vibration, because all tubes are at least to some degree microphonic, and many types, especially some of those with larger glass envelopes, can be very microphonic. Some of the more expensive tube equipment makers (e.g., Allnic) even go to the trouble of isolating tube sockets in an energy-absorbent gel. Without exception, I have found tube preamplifiers (phono and linestages) to benefit from isolation, and tubes benefit from "dampers". As to transistors, according to Wiki one of their main advantages over tubes is a lack of sensitivity to mechanical vibration. And yet, many do use expensive isolation devices, for good or ill, with transistor gear. Those persons would tell us what a huge improvement they experienced. Certainly, CD and DVD players do benefit from isolation, for obvious reasons related to the laser reading the disc.
Now, as regards the F22, in order for that airplane to fly, its piloting computer must be oriented in space at all times, so it can "know" how to maintain level flight and issue the correct commands in response to its pilot. I have no doubt that its piloting computer must be encased in some sort of module that keeps it aware of level flight and is isolated from vibrations, because, like a phonograph stylus, if it is vibrating, even though its component parts are not sensitive to vibration, it might not be able to sense how to create stable flight. Or perhaps it senses its own micro-instability and corrects for that.
