40-50 lights flying over Butte Montana in a V formationMy wife ande I were watching t.v at 9:30 m.s.t. From the south I saw out our window a slow moving vanilla colored orb moving north at a slow pace. My wife went out on the deck to look at it She called me out to look at some others. I went out to see and we saw 40-50 smaller lights coming west over the rocky mtns. They were flying in a V formation. They moved west into a U shapede cloud and as of 22:18 there are still amber lights on the fringe of the cloud. I contacted Spokane tower and talked to Rob Henry and he called Salt Lake City to check the radar. They showed nothing on radar while they were still in our direct sight. I called a neighbor over who is ex military and he said that they were too high for choppers and too sliow for planes. I got your contact info from ((name dleted)).
