While driving on 2 going I noticed a black line in the sky that I thought might be an eagle. No wings, head, tail. Black cigar shape

I was driving on Hwy. 2 moving SE toward Clayton, OK. At first I was noticing contrails in the sky. I saw a black dot way up in the sky thinking it might be a hawk or an eagle. I continued to watch as it got closer to me and realized that it might be a government drone. It had no wings was black and cigar shaped. It was at least 1000 ft in the air and moving from the SE to the NW. I have never seen anything like this. I know what drones look like but this did not have an apparent propulsion system. I do not know what I saw, I did not stop my car to watch as it went above my car. I was not looking for any strange flying object. I cannot unsee what I saw and it puzzles me. I would like to have an explanation of what I saw in the daytime over rural Oklahoma.
