My wife and I were driving south on I-91 in northen Vermont south of St Johnsbury, my wife though she saw a falling star, it was a red and orange traveling at a high rate of speed but it then stoped an hovered about 30 feet over the interstate as we drove under it. After it stopped it was just a white glow about 10 to 12 inch's across kind of star or diamond shaped, there was nothing around and we were not around any towns or lights. I lost sight of it after I drove under it. My wife saw it for about 5 seconds before it hovered and I only saw it for less than a second or two has I drove under it. My wife looked at me and ask "did you see that?" and I said yes. We joke most of the way back to our motel about seeing something like that and wondered what it was.
