It remained unknown Sunday morning what caused a mysterious, explosion-like noise that rattled the windows of homes in Paxton on Saturday night and could be heard in towns as far as 30 miles away. Speculation over what may have happened continued well into Saturday night on social media and into Sunday morning at local cafes and coffee shops. Some wondered if it was a jet that broke the sound barrier during a test run or perhaps a meteor that entered the earth's atmosphere at supersonic speeds. It was at 9:15 p.m. Saturday when the big "boom" could be heard in a swath of East Central Illinois spanning from as far south as Rantoul, Gifford and Ludlow to as far north as Cullom, Gilman and Thawville to as far west as Gibson City to as far east as Milford and Hoopeston. The Ford County Sheriff's Office's dispatch center in Paxton received several calls about the noise, including one person saying they could hear it in Thawville, but no fires or damage of any kind had been reported in Ford
