ray.... Thanks for that post as I have always wondered if anyone else has seen those effects. They can happen virtually anywhere on the air frame or in the screen room, but a bad ground would certainly excite that local area.

On the C5, I can remember seeing bad grounding at the antenna connector for that big, bad Avco HF R/T hung on a piss-poor rack in the tail.
You could see it - a coronal arc around the base of the PL-259 style connector. It would glow in the dark when your buddy hit the TX line in the avionics bay. You could draw it out farther and create an arc by placing the blade of a screwdriver against the R/T mount and edging it up to the faulted connector - but if you slipped a bit and lost the ground connection to the mount, you'd end up with burn on your hand.
Cheers!
