I wrote a simple VBA tool (really short) that integrate ArcMap with Google Earth.
Add whatever data you want in ArcMap and then activate the tool. The tool will open a new internet explorer page with a Google earth plug in.
Now just browse your data in ArcMap (Zoom, Pan etc). You will see that Google Earth will fly to the same location. (Doesn't work with schematics for sure)
Why this is useful? You don't need to overwhelm your ArcMap with satellite images, you have a live source of up-to-date data from Google Earth as you browse your network.
