trial run
Im thinking so!
regardless of the lack of leaked chatter about doing so...
“trial run”
Back in the 80’s they took out several HV power lines at the same time.
I’m thinking we will be like North Korea or some such place where internet, and all other communications will go off during certain hours each day/night.
Wait until a few towers carrying 500kv lines are brought down (one can be temporarily replaced within a few hours but not a string). That's when the fun really starts.
