Eyeballing?

I believe the most famous line I herard in Vietnam was from Carl Cvitcovich down in III Corps, near Tay Ninh. It went like this:

Seconds later the gook disappeared. Later in the day on the way home Carl's LOH had an engine failure and he autorotated into a rice paddy. The aircraft investigation resulted in the finding "pilot error while eyeballing" I picked him up in my Huey and had never seen Carl so pale in my life.

In OCS we called it "dog eyein'", and it would get you 40 pushups. I guess that's better'n E & Eing in the Delta.
