Project 10073 Record Card and Investigation Report — Naperville, Illinois, 26 March 1962

This document details a UAP sighting reported on March 26, 1962, in Naperville, Illinois. Two female witnesses, returning from a bridge party at approximately 11:40 PM, observed red, flashing lights while driving. They initially described the objects as red balls of light that swooped toward the ground near the NCC Fieldhouse. The witnesses reported that the objects appeared to rotate and were stationary when the car stopped, but moved when the car was in motion. They noted that there was no engine noise, which they found unusual for an aircraft. The Naperville Police Department received the complaint, and Officer Givler was dispatched to investigate. The investigation included interviews with the witnesses, who were questioned separately to verify their accounts. While their descriptions of the location, color, and general motion of the objects were consistent, there were discrepancies regarding the size, shape, and specific behavior of the lights. The investigation also involved checking with the Federal Aviation Administration, which reported no aircraft crashes or emergencies in the area at that time. An investigator noted that the spotlights from the Highland School, when viewed from certain angles, could potentially be mistaken for flying objects by someone in the 'right frame of mind.' Despite these efforts, the investigation failed to reach a definitive conclusion, and the case was officially classified as 'Unidentified.' The file includes extensive meteorological data, specifically adiabatic charts, likely used to rule out atmospheric anomalies. The report also mentions a separate, similar sighting reported by a couple in Lisle, Illinois, on the same night, which was covered in the local newspaper, the Naperville Clarion. The document provides a comprehensive look at the investigative process for UAP reports during this period, highlighting the reliance on witness testimony and the challenges of identifying aerial phenomena.
