Greg, Jon,

I usually arrange a safety gap between the bushing and NST
case at both bushings.  Often, only one safety gap fires, 
rather than both.  At least in this case, it's sparking to ground.
My guess is that even using other gap set-ups, one side probably
fires first to ground, and this triggers the other side to fire.

Cheers,
John
