White shimmering cigar shaped object with black stripe down the side, approximately 150' in length.I was driving home from grabbing burgers after church, on Hwy. 29 South. As I pulled out onto Hwy. 29 South, (West Point Rd.) and started driving South, I looked up to my left and noticed, what I first thought was an odd shaped white cloud. As I continued driving South, I could see the clout better and better, until I finally realized that it wasn't a cloud. I could see that it was a Cigar shaped object and it was standing still. I immediately began trying to rule out an airplane, blimp, etc... As I continued down the road, I could definitely see the onject better and could see that it was cigar shaped, approximately 150' in length, with some sort of stripe or dark colored marking down the side. The craft was standing still, motionless, at approximately 2000, to 2500 Agl. I could see the entire left side and one end and I observed it for approximately 20 seconds. Then, it suddenly dissapeared right before my eyes. I was trying to process what I saw, because I know what it was not. It was not an airplane, glider, jet, helicopter or any other known conventional aircraft. It was a shimmering white cigar-shaped craft, with a black looking stripe down the left side. I am certain of what I saw and I was on the phone with my wife the entire time,,describing it to her. I am a 51yr. old licensed pilot, with over 1000 hours.
