A friend and I had received permission to take some night time photography at Grandview Cemetery in Chillicothe. We had just finished up and were walking back to our vehicle when I noticed something streaking in the sky. I yelled to my friend, "Whoa, look at that," and pointed to the object streaking toward us. At first I though the object was a meteor or something due to the speed it was coming toward us. But as it flew directly overhead, the object reflected the city lights and I could clearly see it was actually a rounded triangle, meaning the corners were rounded, not pointed. The object continued from the northeast to the southeast at a quick pace and was quickly out of site. The entire length the object was in my field of view was about six seconds. Unfortunately my buddy, who was in front of me, thought I was yelling about something going on in the city below and didn't look up in time to see the object. The sighting was so quick that I couldn't properly gauge the object's size or elevation. It did fly directly over my head and I got an excellent look at the bottom side of the object. The object appeared to be solid and metallic and did not contain any type of navigation lights. It made absolutely no sound as it passed overhead. I was initially confused as to what the object may have been and my adrenaline was pumping. I stood in the area for a few more minutes to observe if any other objects came through, but nothing else happened.
