I looked up and over as I was on my way to work. As I looked up I saw a cigar or disc from the side was white but not reflective and just sitting behind the power lines at first I thought it was a plane. Then after a few seconds I noticed the plane was not moving. I asked the driver to look he said he saw something, and I watched for at least 5 - 6 seconds, when the trees blocked our view we decided to turn around and take a look again. The object was gone. It definately WAS NOT an airplane - there was no wings and it was hovering still.
