Good evening, I just witnessed a similar event here in Omaha, Nebraska USA. My roommate and I for the last thirty minutes watched as a group of 3-10 orange bulbs flew from the northern sky to the southwest sky and occasionally north to east.
We witnessed 10 groups fly over. Neither of us have previously seen a UFO, our third roommate suggested maybe they were birds lit up by the city lights. They were moving from the northern sky to southern and out of sight within 10-12 seconds.
Higher than a plane, and moving much faster than a jet or satellite. I was amazed at what we saw, came inside after 10 minutes of no sightings. And Google this topic, saw your post maybe they are related. Keep me posted if you hear of other stories similar to this.
Feel free to pass this information on. Thank you.
