Simulation of an alleged sighting of a UFO (unidentified flying object) near the small town of Belleville, Wisconsin, USA, during a cold March night in 1987. For several months previously, the town was plagued by UFO sightings, from simple groups of lights to cylindrical objects rising from forest clearings in broad daylight. This sighting was witnessed independently by widely scattered individuals, & Illinois Air Traffic Control verified the presence of an unidentified object in the vicinity at the stated time. It was one of several nighttime & early morning apparitions reseached by UFO investigators from Chicago.
