Manuevering bright objects in the western sky, leaving short contrails, disappearing and reappearing.I was going from Childress Texas northwest to Memphis Texas when I saw a small bright circle in the western sky above the setting sun. It was very bright like a star. It just hung there for a few minutes. Then it disappeared. Soon it reappeared then I saw a short tail from it like it was a jet beginning to leave a contrail,however it was very short and then disappeared. Then I saw another one and the same thing happened. A long light appeared like a small cloud then it bloomed into a long streak, however it could not have been a cloud that developed so quickly then it evaporated. I watched this activity until I made a turn and then it went behind a cloud. I have seen the shiney sphere before not not doing manuevers. I had decided it was a weather balloon until it left a trail behind and started moving in and out of sight.
