Unidentified string of ball lights seen in valley of Shaftsbury, near Rte 7A..heading South to Bennington spotted off Old Depot rd.While walking my dog at night, I saw what appeared to be lights in a string across the sky. I thought a plane was low-flying and perhaps ready to crash..I thought the lights I saw were strung across the front of the plane and wings. However, there was absolutely no sound to be heard from the object. I then supposed I maybe saw a searchlight going across the mountains but it did not really make sense since I heard no sound of either a helicopter or plane. It appeared to be a string of beaded lights in a horizontal pattern. I ran inside and got my daughter and son to come out and look at the strange object, since I had no clue what it might be.My mom brought my brother and I outside to see some sort of object...I asked her what it was that she was taking us to look at but she didn't know. At the time I thought she had seen a wild animal in the woods and wasn't sure of it. When we were outside we went to the top of the driveway and looked out over the mountains. We then saw about 50 lights-ones you might see on a passing airplane, none flashing- about halfway down the mountain. It moved slowly across the mountain in a horizontal fashion, with a few lights disappearing from the left, and then reappearing on the right. It gave a creepy sound, one that you might hear if a person was trying to sound like a ghost...one you might hear one an episode of the Twilight Zone. The sighting of this object frightened me and I wanted to go back inside, which we did. When we got inside, the object was gone with the sound from our view, down south towards Bennington. My mom and I were baffled of what it might be, thinking of all we could, we only came up with ideas like "A stealth plane" or "A helicopter sending out a search light across the mountain", none made any sense...except a UFO.
