IC's can be hardened to prevent damage from EMP. Today's combat aircraft have a lot of solid state devices yet they consider the Aircraft to be nuclear hardened. The trick is to collect the emr's (electro-magnetic radiation) and dissipate it. Remember dealing with the debates on repairs on our Aircraft when I was in the Air Force, we had to be real careful about any wiring harness that was shielded to insure we didn't mess up the shield and we maintained all grounding and bonding of components. When I moved into an EOD slot some of the fuzes and other components were EMR sensitive so some of the render-safes involved a technique called WIF (wrap in Foil) or bed it in a sand filled steel ammo can. Much equipment is tested for EMR interference, a lot of cars and equipment used to go to upper Michigan and be tested on the ELF line up there to see if could get scrambled by the EMRs. They also test the vehicles to insure they don't emit EMRs that could mess themselves or other vehicles up. I'm waiting for someone to try using the EMR excuse for runaway vehicles.

And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
