Gary, I suppose I wasn't implying dicey-ER technology -- just more of it. Compared with WWI (and some Golden Age) models even the WWII stuff in more complex. And more technology just means more things to potentially fail. I admire the guys who are willing to master this technology but it's not for me.

Anyway, the point of this thread was just to offer up a curious and different modeling challenge that I happened to come across.
