At 7:05, a fireball UFO traveled southwest from Eagle River.I was driving to eagle river when I saw an orange glowing object in the sky. By my estimate, the altitude of this orange ball was somewhere around 10000 feet. It shot over the mountian with incredible speed, yet it never made a sound I could hear. It went out of sight behind some trees, but was heading in a southwest direction. I got on the highway going southwest toward anchorage. This took about 20 seconds because I had to go through a school zone. When I got on the highway, this abnormally quick fireball was almost out of sight. It had easily made it east of anchorage where it appeared to stop, pulsate a few times, and disappear. I know this fireball was travelling over the speed of sound. I know when I'm looking at a jet or helicopter. It was neither. This was not earthly, and it did things we cannot.
