You all caught the small issue and missed the big one, the short mean
free path of electrons at low altitude prevents them from generating
much of a pulse outside the blast radius.

Compare 20KV/meter to a lightning strike, which power lines, aircraft
instruments and radio towers generally survive. Several years ago it
hit the pole outside my house and fried the phone line protection
circuit, but didn't damage the cheap electronic phone connected to
it.

That's the way it goes. When you have expensive equipment - the
equipment blows to protect the fuse.
