I was out watching meteorites. News said good night to see them. After a few minutes of watching I noticed a star disappeared, I took a second look and realized something had flown in front of the star. That's when I realized what I was looking at. It was huge, the largest flying thing I have ever seen in the air.It was just slightly different color the the sky itself. in the shape of a V . There were no lights, or sound. It was flying south towards salt lake city.it only took about 6-9 seconds before. The light pollution made it impossible to see. And it was gone. What realy took me back was the size of it. It was huge and very fast.I waited to see anything else but nothing happened.it was 10:00pm when this happened.i was super excited. I have only seen 2 UFOs in my life. With over 30 years between, sightings.
