I was driving so I only got a short glimpse, but it appeared to be a Boeing BBJ with winglets. It was white, with some blue along the fuselage and up on to tail. I dug around in the photo database and this is the closest image that I could find.

The only difference is that the plane I saw appeared to have more plugged windows. I checked flytecomm and couldn't locate anything fitting the bill, I'm guessing its some sort of charter. I also have a hard time believing that the Samsung corporation, the owner of the above jet, would come into CVG. Can anybody help me out?
