My friends and I witnessed 4 objects of orange light moving across the sky in formation for about 40 minutes.I was standing in my yard smoking a cigarette with my friends when I happened to look up at the sky and notice a ball of an orangish light fly across the sky between two trees in my yard. The night sky was completely clear and no clouds were in the air so I could see the object of light quite clearly. The light moved too fast to be an airplane, produced no sound, was at a hight of about 200 feet or 300 feet, and seemed to have a small haze around it. At first it was on a southwest trajectory, but then changed immediately to a west north west trajectory. At first I thought I just was seeing things or got too much of a buzz off my cigarette. However, after talking with my friends for another 5 minutes I decided to look in the sky where I saw the object. After watching for about 45 seconds I witnessed 3 more lights move across the same area of the sky in a southeast trajectory in formation. Startled I let two of my friends know what I had seen. We decided to go to the backyard where there was less light and trees to see if we could all see the objects I witnessed. After being outside for about 2 minutes laying down on a blanket we witnessed four objects move from the west part of the sky to the eastern part only to disappear over the city of Natchitoches, Louisiana. All four lights were moving in formation in the same direction. For about another 30 minutes we watched the sky and only noticed the four objects of light once more above the city of Natchitoches before a thick layer of clouds began to move in. We do not know if it was only four objects that we witnessed in the sky or if it was a total of eleven objects of light that we witnessed in the sky.((NUFORC Note: We believe that the possibility that the witness may have been observing advertising lights would have to be ruled out, before we could conclude that he was looking at genuine UFO's.
