As a kid, I was in an astronomy group and knew the skies well. First time I saw a discoteque lights in the sky, I was sure I am seeing an UFO. I noted down the time and place but realized since it was in the sky constantly that it can't really be an UFO. Later I learned it was just a reflector pointed to the sky. I wouldn't be surprised if a similar effect but from car lights or plane lights could throw people off. Since it could be a one time event, it's hard to explain it.
