These are the coordinates of where I viewed this unidentified flying object. The object was long, containing lights. Imagine a biplane pulling a banner with lights, had to have been a city block in length.
It was in Mount Greenwood, ILLINOIS. Time of incident was 1839 on the 12th of February. I observed the object for a minute in total and watched it disappear. Unsure if flew into a cloud or disappeared completely.
