Incident #127 — Yugoslav-Greek frontier — 7 May 1948

This document contains a report regarding Incident #127, which occurred on 7 May 1948 near Lake Doiran on the Yugoslav-Greek border. The report includes a statement from a Captain (name redacted) of the 51st Air Base Group, 50th Air Transport Wing, who observed an unidentified object while in flight. The witness described the object as resembling an artillery shell or 'shrill mine' and noted that it appeared directly on the course of the aircraft at an altitude of approximately 3,000 feet. The witness reported that no sound was heard from the object and that there were no other witnesses to the event. The weather conditions at the time were described as 5/10 to 5/10 cumulus clouds with tops at 6,000 feet. The report explicitly states that no photographs were taken and that the occurrence had no observable effect on the aircraft. The official assessment, included as part of the Project Grudge report, concludes that the information provided is too limited to draw any definitive conclusions, though it suggests the object may have been a meteor. The document includes administrative correspondence between the 550th Air Transport Wing and the 51st Air Base Group regarding the transfer of the witness and the processing of the report. An incident index from the Project Grudge report is also included, which categorizes Incident #127 under the section for non-astronomical sightings where a lack of evidence precludes a definitive explanation.
