Mad Jock,
The specific one I was thinking of was American Airlines into Cali. Here are a couple of quick summaries.

A more detailed analysis
In reviewing them, I must admit I may need to take back my comment. While the first two links suggest a system similar to yours, that is a text list of waypoints bearings and distances, the third link implies they did have a moving map and didnt notice the wrong R entry showing a line zooming off to Bogota to the North East.
I can easily see how entering the wrong R NDB into a text based FMS can get you, I do struggle with not noticing that the magenta line takes yoz 150 miles behind and to the left of where you are going.
