I was riding my motorcycle to my friends house just a couple of miles from my house

I was riding my motorcycle to my friends house one night. I saw what i thought was a small low flying plane in the distance that was traveling almost straight towards my direction. I turned on my friends road and this craft also turned in the same direction. It was flying at exactly the same speed I was and staying almost directly above me. At this point I thought it was a helicopter that happened to be going the same direction as me. I got to my friends house which had a big tree in the yard that blocked my view of the craft. My friend wasn’t home so I got back on my bike and headed back home. When I got back on the road the craft was still there. If stayed almost directly above again. I got to the stop sign and cut my bike off and removed my helmet. It was a perfect triangle with a white light in each corner with two small red light between two of the white lights. According to its orientation as it traveled, the red lights were on its rear. It hovered silently and completely still. This thing was pretty low. Id estimate 500 feet. There was no evidence of any wind being generated or any noise at all. I started my bike back up a rode off. It slowly headed north east which is the direction of red stone arsenal and Marshall space center. I’ve seen other craft in this same area as well but this was by far the hardest to argue with. I’ve done some research and found the tr3b astra. That is what I saw. It is absolutely real
