Project Grudge - Unconventional Aircraft Sighting at Klamath Falls, Oregon, 23 June 1949

This report details an investigation into a sighting of unidentified aerial objects near Klamath Falls, Oregon, on 23 June 1949. The investigation was conducted by the Office of Special Investigations (OSI) following reports from multiple witnesses, including CAA maintenance personnel at the Klamath Falls Airport. Witnesses described observing four or five oval-shaped objects, approximately the size of a dinner plate, flying in a trail formation at an estimated altitude of 25,000 to 30,000 feet. The objects were reported to be grayish-white or metallic in color, moving at speeds estimated to be faster than any jet aircraft, and exhibiting no exhaust trails, appendages, or visible means of propulsion. The objects were observed for approximately three to four minutes before performing a sharp turn and fading from view. The investigation included interviews with several witnesses and a review of weather data and flight records. The OSI determined that there was no evidence to suggest the objects were anything other than conventional aircraft, noting that no military or research testing devices were active in the area at the time. The report concludes that the sighting remains categorized as aircraft, as no data was presented to prove otherwise.
