11:42 PM Billings MT. Outside with my dog in anticipation of New Year's fireworks. Saw what appeared to be a rocket/firework in the southwest and pointed it out to my dog. He got spooked and then trotted home to the front door and waited. I kept my eye on rocket, but it did not burst. It was then that I felt the object was odd. It was bright orange traveling NE in a steady path. I had a pad computer looking at Google Sky and then fumbled and made a one minute video clip. A second fireball appeared in the same path as the first. This is the object best seen in the video. The objects flew below airliner altitude and were silent (the night was quiet and I would have heard any engine noise). The objects continued NE until out of site, the whole event taking three minutes in my estimation. I saw a couple of posts of a similar nature right around the New Year - very interesting.
