Oh, I get it, a traveling virtual ground. Is this virtual ground at 
the same potential as the real ground from where it was 
launched?  Maybe someone could devise an experiment to prove this 
virtual ground exists and it's potential relative to the real ground 
potential is the same as it must be, if there is a true return path.

Otherwise, the weapon shooter would not be concerned if the EM wave 
took along its own ground path.  No return path back to the shooter 
is necessary.

So, on a cold dry December morning Terry is walking in his leather 
shoes across his carpet.  As his hand reaches for the well insulated 
front door metal handle a sharp snappy little spark arcs between his 
index finger and the well insulated metal door knob.  Has the door 
knob potential changed?

Where is the return path?
