UAP Sighting Logs: January 1956 – December 1956

This document is a comprehensive chronological log of unidentified aerial phenomena (UAP) sightings reported throughout the year 1956. The logs are organized by month, beginning with January and concluding with December. Each entry provides the date of the sighting, the location, the type of observer (e.g., military, civilian, multi-observer, or specific pilot/radar reports), and an official evaluation of the event. The evaluations reveal a wide variety of explanations for the reported phenomena. Many sightings were attributed to astronomical events, such as meteors, stars, or planets like Venus, Mars, and Sirius. Other common explanations included weather balloons, conventional aircraft, and weather conditions. A significant number of entries are marked as 'Insufficient Data,' indicating that the information provided by the observers was inadequate for a definitive identification. Throughout the year, several cases were categorized as 'Unidentified,' and some were noted as 'Case Missing.' The document also includes a section for 'Additional Reported Sightings (Not Cases),' which lists reports derived from news clippings, letters, and other sources that were not formally investigated as primary cases. The logs reflect a global scope, with sightings reported not only across the United States but also in locations such as Hungary, Japan, Morocco, Bermuda, Afghanistan, France, the Taiwan Straits, South Africa, Egypt, Finland, Denmark, and the USSR. The document serves as a systematic record of the reporting and evaluation process for aerial phenomena during this period, highlighting the military and civilian efforts to categorize and explain these occurrences.
