I always see this at night. So, this is what happens. I will tell about one time I saw them. The most impressive. First, I am sure this is some military thing. It could just be planes. But, the way they move. It is like nothing I have ever seen. It like, goes forward and stops. Almost looking as if it goes back a bit. One night, I looked and saw one going left and right. Then, I looked on the other side and there were two. One on the left and two on the right. Then, I looked back at the one and there were now three. So it was three and two. I looked back at the two an there were four. So, it becomes three and four. Then, I looked back at the three and there were five. Five and four. Just going back and fourth. Left to right. Then, they are gone. I went outside once. I get never get them on my phone. They make no sounds.When my mom was a kid, her and my grandparents, aunts and uncle looked out and something almost landed right in their yard. It was really bight. That must have been in the 70s. It was in Maryland, around a campground.
