I was driving my car around 9:30pm near Amesville,Oh which is right outside of Athens,Oh, while driving I noticed what I thought was a star at first but it was way bigger than normal & not high enough to be a star & it was like a bright orange ball so I stopped my car to get a better look. About 8 seconds later it started pulsating orange & blue lights & then the object took off at a very high rate of speed across the sky & then shot straight up into the air until I lost sight of it. After the object ascended straight up I started driving in the direction in which the object flew away & I saw no other lights or crafts of any kind. I was in the U.S army and served in Iraq I've seen numerous types of aircraft & this was absolutely not any of those!!! I have never seen anything like this in my life! I was actually shaking after the sighting I think maybe from my adrenaline pumping from seeing something I thought I would never see in my lifetime!! The entire sighting only lasted about 15 seconds at the most but it was long enough to understand what I'd just seen!
