Too high up to smell, plus it is vert cold and windy today. Gusts are up to 18 mph. The one in the pic I saw in the day time and figured it was a new type of drone that I had never seen before. The one with four wings came towards my house late at night, around 3 am. It flew towards me as I was carrying my dogs hind legs who was paralyzed from gout and needed a nature call. At first I thought it was a bat, then an osprey, then bewilderment. As it flew over my head the tail flared in the bright mother of pearl pastels. It was about 10-15 feet higher than my house. I just smiled and said God Bless. Who is them?
