Large string of bright lights in a chevron formation

While outside talking on the phone on Monday Feb 13, 2023, I first saw a large sphere of light illuminate in the northeast horizon. It was much bigger and brighter than any meteor I have ever seen. It did not move. It stayed lit up for approximately 5-10 seconds and then disappeared. Less than 30 seconds later, in the northern sky, just west of the light I had just seen, a large string of lights in the formation of a chevron, illuminated in front of me. They did not move. Each light appeared to be rectangular. This was a huge formation of lights. Much larger than any single aircraft known to man. The lights didn't move but simply went out after 15-20 seconds. I ran to the door and yelled for my wife and son to come outside. Within the next minute or two, the string of lights illuminated again, but the formation had changed slightly from the original chevron. They only lasted for 20-30 seconds again before going out again. For several minutes before the first spherical light was seen, a deep growling jet-like aircraft noise was heard. This noise seemed to get faint at one point, as if a jet was traveling away from us, then its growl increased and stayed in the air for several minutes after the lights went out. The noise was heard for approximately 20 plus minutes. Our home is on a high peak of a hill in the foothills of the Ozark mountains and aircraft noise is always louder because of the reverberation between the hills. That reverb sometimes makes it hard to pin-point exactly where the sound was originated. We could not say for sure the jet sounds were from the lights, or possibly even military craft tracking the lights. It is important to note that our home is approximately 8-10 miles from an active nuclear power plant.
