Project Grudge Incident Report — Ludington, Homer, and Vandercook Lake, Michigan, 1949

This document is a formal report of investigation conducted by the Office of Special Investigations (OSI) under the auspices of Project Grudge. The report details inquiries into incidents in Michigan, specifically focusing on reports from Ludington, Homer, and Vandercook Lake. The primary incident at Vandercook Lake involved a report from Mrs. Leroy Drinkwine, who observed an object fall to the ground and burn a hole in the pavement. The object was described as glowing without a flame for approximately three minutes. Following an investigation by Special Agent Jack L. Heckelman, the residue from the site was analyzed by the Clark Equipment Co. laboratory. The laboratory concluded that the residue was consistent with a railroad or truck flare, commonly used as an emergency signal. The report includes a photograph of the burned area and a clipping from the Jackson Citizen Patriot dated 27 July 1949, which confirms the laboratory findings and identifies the object as a 'fusee' or flare. The investigation concluded that the object was not a meteor or other anomalous phenomenon, but rather a standard emergency flare. The file was subsequently closed by the 5th District Office of Special Investigations, as all logical leads had been exhausted.
