Three craft seen circling at what appeared to be very high altitude from multiple airline crews who discussed it over Guard Frequency

We were flying for a major airline on a red eye from Las Vegas to Cincinnati. Throughout the first two hours, we heard chatter from other aircraft on Guard Frequency and one ARTCC frequency about strange sightings (the first was over Pueblo Colorado by a Fed Ex flight if you get any reports on that...they reported that a meteor exploded and many aircrew chimed in on it as did the controller on the ground who joked that he didn't have the best view). Over an hour after the Pueblo incident, we heard some more chatter from other planes. They were all seeing something. Some time after hearing the other planes report sightings, the Captain said "Whoa, you see that???!!!" I didn't see the first one and responded "No, what did you see?" He said "it looked like a slow moving meteor." We had the cockpit lights on full bright to stay awake so we decided to turn them off and adjust our eyes to the night. Once we did, I saw what he was speaking about. It appeared well above the horizon and at what appeared to be a decent distance away. It fizzled like a sparkler and was brighter than a parachute flare we used in the military when I flew jets for the USMC. As we watched the bright object, another flew by it and became bright and the bright one fizzled to dim then disappeared. Then we saw a third circling with the first two that was very dim but would occasionally flicker bright. These were not satellites, stars, Venus, or autokinesis induced trickery. Everyone was seeing them and reporting them over guard. There were no clouds and the weather was Clear and Visibility Unlimited. One craft we saw did a sharp turn at a great speed, which we got on film. I would like to remove our voices from the film prior to submitting as I do not wish to throw the Captain under the bus. If anyone at NUFORC can assist with this, I would appreciate it and will turn over the best video. I will submit another with this report that is not nearly as good but shows one of the craft. The best video shows the craft turn at high speed at the 17 second mark. It is surreal to watch but I would like to remove our voices for anonymity.
