Project Grudge Incident Report — Ludington and Homer, Michigan, April 1949

This document is a formal Report of Investigation under Project Grudge, concerning unidentified aerial phenomena sightings in Michigan during April 1949. The investigation, conducted by the Office of Special Investigations (OSI), covers two primary incidents. The first occurred on 21 April 1949 in Ludington, Michigan, where two high school students reported seeing a white, comet-like object with a long tail traveling west over Lake Michigan at an estimated altitude of 5,000 feet. The object was in sight for approximately 10 minutes. The official conclusion for this sighting was 'AIRCRAFT'. The second incident involved employees of the Pet Milk Co. in Homer, Michigan, who reported sighting six flying discs on 29 April 1949. These witnesses pursued the objects in an automobile for five miles along highway M-60, describing the objects as approximately 10 inches in diameter and moving in wide circles. Additionally, the report details a separate investigation at Vandercook Lake, Michigan, regarding a burned hole in the pavement. This was investigated by Special Agent Cene P. Moritz, who concluded that the residue found at the site was likely from an emergency flare, noting that the witness appeared to be enjoying the attention the incident generated. The report includes various enclosures, such as newspaper clippings from the Grand Rapids Press and the Detroit Free Press, as well as photographic evidence of the burned area at Vandercook Lake. The investigation was closed on 14 September 1949, with the Air Materiel Command determining that all logical leads had been exhausted.
