Cigar shape craft with lights inside over Charlotte, NC.

My ex-wife and I were sitting at a red light at the intersection of Independence blvd. and Idlewild Road.  We were facing North.  We notice to our right about half a block away some type of flying craft just above tree top level.  It was moving very slowly.  It appeared to be silver in color, cigar shaped and had a row of windows on its side.  It appeared to have lights on inside.  
At first I thought that is was a airliner flying very low and I even tried to see any people sitting in the craft.  However, we soon realized that this was not a airliner.  When the light at the intersection turn green, we crossed the intersection and went into the parking lot of a large bargain store. 
I parked the car facing east.  We observed the craft continuing to travel across Independence Blvd. at a very slow rate of speed.  We also noticed that everything became real quiet.  We could not hear the traffic nor could we hear our vehicle running although we could hear each other talking.  
We were able to get a good look at it as it crossed the highway.  Although it appeared to have lights on inside, we did not see anything or anybody inside the craft.  As the craft reached the center of Independence Blvd., it stopped, hovered for about a minute and then began to travel toward the east over the highway.  Although it was now heading away from us, we never lost sight of the row of lighted windows that were facing us.  We watched the craft until it disappeared heading east.
Source of report indicates that the date of the incident is approximate.  PD
