Hi Chris,
     Yes some serious mechanical engineering involved!
My good friend Marshall designs vlf antennas for the military and has
worked on NAA.
In fact Marshall worked with Dr. Wundt, the fellow who built the
Goliath vlf antenna in Germany in WWII and was later brought to the
U.S. in Operation Paperclip. Wundt did the original design for NAA.

Great stories!
