UFO Government Files
This dataset is a local staging copy of the publicly released U.S. government UFO/UAP files from the May 8, 2026 release.
It is organized for direct upload to Hugging Face Datasets and is intended for archive analysis, metadata review, and reproducible document inspection.
Context
Based on the tremendous interest shown, I will be directing the Secretary of War, and other relevant Departments and Agencies, to begin the process of identifying and releasing Government files related to alien and extraterrestrial life, unidentified aerial phenomena (UAP), and unidentified flying objects (UFOs), and any and all other information connected to these highly complex, but extremely interesting and important, matters. GOD BLESS AMERICA!

Notes
- The source release contains 162 metadata rows, but two video items are duplicated, leaving 159 distinct documents.
metadata.csvandmetadata.parquetare deduplicated onOutput Path.metadata_raw.csvpreserves the exact exported table before deduplication.- Missingness is concentrated in
Incident DateandIncident Location, so the dataset is best suited for descriptive and archival analysis rather than direct quantitative inference. - The local file tree preserves the source agency structure so documents remain easy to trace.

Suggested Use
This dataset is a good fit for:
- metadata analysis
- document classification
- archive mapping
- agency comparisons
- descriptive evidence review
It is not, by itself, a basis for claims about physical origin or provenance beyond what the source records state.
