It is a line-of- sight effect and the inverse square law does not apply.

What - a new branch of physics has been discovered?

Can you explain, why electrical components that are turned off and have no electricity running through them will not just be damaged but 'destroyed' by a high atmosphere EMP?

Thanks for your insights on this thread.
