My family and I witnessed these strange amber lights in Tucson on our way home from dinner. There were seven or eight of them crossing the sky, some solo, and others in pairs flying very very close together. We know these objects were not far from us because my parents live on the other side of what Tucsonans refer to as "Cat Mountain" so they could not have been too far away at the height they were flying or they would have been obstructed by the mountain. These object were silent. Living in this part of the country we often hear fighter jets from the Air Force base, but we are used to that and it is always recognizable and very loud. This was not that... Also occasionally we see squadrons of choppers fly in this area fairly low, but they are always very loud as well and have a distinct sound. The objects we saw tonight were silent and moving across the sky very fast. The objects that were paired were flying closer together than I have ever seen any kind of jet or plane fly at that speed, and they never separated or drifted apart from a uniform distance. They moved from south to north and then one by one or in a pair they vanished never to reappear in pretty much the same place. They did NOT fly out of sight, or go behind any cloud cover. There were no clouds this late in the evening and they never reappeared. These were not flashing lights, you can see about half way I think in the video after I zoomed in a little bit that there was a plane in the distance with "typical" flashing plane lights and then you could tell the ones we were seeing were larger and not flashing. Not sure what we were seeing, but I never really believed in this sort of thing until tonight. Glad I had my phone to record.
