I was spending the weekend at my parents house a couple miles south of Princeton, Texas. They live on 50 acres and it's really quiet and private. My cousin lives on a adjoining 35 acres north of my folks and we were standing in the middle of the road about 9:00pm discussing improvements to the land when we saw two white lights in the eastern horizon approaching us very rapidly from east to west. We wondered what could be traveling so fast! As they flew over and directly in front of us I thought its two fighter jets on a practice run. But there was absolutely NO sound or engine nose!!! Perfect silence. And as they flew over and passed by both lights faded out and they disappeared. We both thought we were about to hear the sonic boom once it caught up but nothing ever came. We knew then we just witnessed something "out of this world" or some sort of top secret aircraft. As the two crafts passed over and just before the lights faded out we could see what looked to be some kind of shinny surface that appeared to be like wings on a aircraft. This was possible with the aid of the "Super Moon" that was rising about the same time. They flew in tandem but slightly diagonal from each other, not directly below or side-by-side. They were flying very low to be typical aircraft. Hoping someone else saw what we saw and can help confirm.
