Project Grudge Incident Report #319 — Boise, Idaho, 13 May 1949

This report details the investigation into a sighting of unidentified aerial objects near Boise, Idaho, on 13 May 1949. The primary witness, a newspaper reporter and former World War II B-24 pilot, was driving from Caldwell to Boise on U.S. Highway 20 when he observed a silvery object in the western sky. Shortly after, five additional objects appeared in a V-formation. The witness described the objects as half-circle shaped, with a point in the center of the front arc, silver on top, and black on the bottom. He estimated their altitude to be between 12,000 and 14,000 feet and noted that they performed maneuvers including a spiral let-down and a rapid climb in a southwesterly direction. The witness stated that the objects appeared to be intelligently controlled and were larger than a B-29 aircraft. The investigation, conducted by Special Agent J. E. Kuttler of the Office of Special Investigations, included interviews with the witness, checks of local weather records, and inquiries with commercial airlines and the Idaho National Guard. Weather records from the Boise Municipal Air Terminal confirmed clear conditions with high cirrus clouds. No commercial or military flights were identified in the vicinity that could account for the sighting, and no radar contacts were reported. The witness was deemed to be of above-average intelligence and of good character. The case was ultimately closed and referred to the Office of Origin.
