🇺🇸 USAF — Project Blue Book
In February 1967, an officer at Sioux City Air Force Base in Iowa reported an unidentified flying object in the sky. The document, filed by the Foreign Technology Division of the AFSC, describes an unusual craft that did not conform to standard aviation norms. The witness, trained to identify aircraft and other aerial vehicles, could not determine the object's origin. The detailed description suggests a serious and professional observation, free from paranoia or speculation.
The report, though brief, includes specific data such as time, exact location, and a preliminary assessment. No threats were recorded, nor were any military responses triggered, indicating the incident was not considered an emergency. Despite the lack of definitive conclusions, the report reflects the authorities' concern for any unidentified aerial phenomenon. This case is part of a series of sightings that contributed to the UFO database of the time.
