Metallic shiny UFO over West Union, Illinois

On January 30, 2018, a shiny metallic round-shaped UFO is appeared over West Union, Illinois.

Witness statement:

While i did not see it myself this event was witnessed by numerous people over the course of about an hour. Said to have hovered there then was gone. Being involved in aviation for the last 20 years i have a bit of an idea what should be up there and what shouldn't. Though i didn't see it with my own eyes i have seen numerous events in this are that i sure can't explain.
