This occurred many years ago, when I was around 12 years old. I have never forgotten it all these years. I reported this to project blue book. I never heard anything back. I was sleeping outside in my back yard with a friend of mine. My friend was asleep and I was awake, watching the stars. The sky was crystal clear with no clouds. The object came from the south, and was HUGE. From one end of the delta wing to the other covered nearly the entire horizon from east to west. It had to have been at least a mile across, maybe more, and a half mile long. There was no mistaking what this was. I knew what the shape was because it blocked out the stars. I've never seen anything like it since. The bottom of the object was covered with symmetrical small, white lights. It made no sound at all, and was traveling at a very high rate of speed in a straight line from south to north. It took only a few seconds to travel from the southern horizon to the northern horizon. I couldn't believe my eyes. I tried to wake my friend, but by the time I woke him, it was gone.
