Welllll, I wasn't going to get into that since there is much misinformation here about that. I did a study about the difference between a solar flare and a NEMP, which I posted on another website. There was a federal commission (pre-Obama I think) that investigated what would happen in a nuclear electromagnetic pulse (NEMP) attack. Scientists tested regular cars, police cars, and ambulances to see what would happen. Very little did - a few turned off but worked again when started. On the ambulance, a computer used to input data turned off but started again when rebooted.
The result was, all cars and trucks will work but some may turn off but start again.
That report is 180 pages long. The car/truck testing material starts on page 114. You can read the report here:
How would those cars be refueled if all the refineries were toasted?
Cars still ran fine post Katrina. Gas availability was a big big big big problem however.
If it is not on (not in standby by) it should come back on is my understanding.
If I read it correctly, aircraft is not immune to EMP-related electronic failure. Radar control would be vulnerable if more than one block was affected.
I’m not worried about an EMP attack. It’s way down my list of concerns. But I see many other paths that lead to a similar grid-down outcome, which also takes down the Cisco network/the internet, and the commo satellites after a few weeks, throwing our cities in to disorder, chaos and violence.
