This document consists of a Project 10073 Record Card and an associated teletype report regarding an unidentified aerial phenomenon sighting in Hillsboro, Illinois, on January 2, 1958. A civilian witness reported observing a white, bright burst of light that lasted between two and four minutes. The witness described the event as being accompanied by a sound resembling a clap of thunder. Initially, the witness suspected the light might be from a vehicle, but concluded it was too bright for car lights. The report indicates that the sighting occurred at night under clear, moonlit conditions. The military investigation, conducted by the 98th ACWRON at Belleville Air Force Station, involved coordination with the St. Louis Ground Observer Corps and the Illinois State Patrol to gather further information. Despite these efforts, no further information was received by May 1958. The official conclusion recorded on the project card is that there was 'Insufficient Data for evaluation.' Furthermore, the comments section explicitly states that the light was observed on the ground and did not fall within the official definition of a flying object.
