Bright white circular light/craft in sky shoots down to 200-300 ft above ground, hovers, than shoots back up at extremely high speedIt was about 3:30 or 4 AM soon before I was going to go to sleep. I have one of those green laser pointers and I thought why not go out and look at the stars for a little bit because it was one of the clearest nights it had been in a while. To add to the darkness and clearness in the sky, one of my neighbors who always keeps his back light on happened to leave it off that night, so it was about the darkest I've ever seen it in my backyard.So I’m out on my back deck looking at the stars, shining different patterns and pointing out some constellations with the laser pointer for about 30 seconds to a minute, and all of a sudden a bright, round white light illuminates in the sky appearing to be about half the size of the moon at first. From my position, I was looking up at it at about the 12:00 position but it was not directly above me, a little bit in front of me. It was hard to tell how high up it was but it looked like it could have been star level. Right when I saw it light up, it really took me by surprise and I was just thinking like what the hell is that thing.This is where the story gets hard to believe. After the object illuminated and appeared to remain still for a second or 2, it shot down from sky in in a complete vertical line to about 200-300 ft. above the ground (about 4-5 full tree lengths based on the trees it was above in my backyard), in only a matter of seconds. When this happened, I was in complete shock and awe and dropped my laser pointer, just standing there and staring. The light was so bright that it almost hurt my eyes but I couldn’t look away. It seemed to be about the size of a car but completely round. When it shot down, it was moving at speeds much faster than any type of aircraft that I’ve ever seen. When it came to its stopped position, the light bent a little but then went back to its circular shape. The light was completely white and like I said almost a little bit blinding. Also, since I was looking up at it, it seemed like I was looking at the bottom of it and didn’t have a side-view, so the c! ircular shape that I saw may have just been the underneath of the structure. It also emitted a soft, really low frequency sound as it hovered there but there was no sound when it was coming down. It stayed completely still and hovered for about 5 seconds. It truly felt like as I was staring at it, it was staring right back at me. And then all of a sudden it shot strait back up into the sky vertically in the same path at an extremely fast rate of speed about equal to how fast it came down. But when it shot back up it reached a certain point in the sky, and then paused for a second, then shot off westward at a sharp angle and then quickly disappeared. One of the craziest parts to me is that I don’t even live in the woods or out in the middle of nowhere. I live in your average suburban neighborhood.Right after it happened, I went back in the house and went to bed immediately. I thought about waking my dad up to tell him but it was really late and I was kind of trying to convince myself that I didn't really just see that. I don’t want to tell a lot of people because I know that this story seems pretty crazy, but I know what I saw and I’m not lying.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
