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!

Contents

  • metadata.parquet: cleaned canonical metadata table
  • metadata.csv: cleaned canonical metadata table in CSV form
  • metadata_raw.csv: exact export of the source metadata
  • files/: mirrored PDFs, videos, and images organized by agency

Dataset Snapshot

Metric Value
Raw metadata rows 162
Distinct documents 159
Agencies 4
File groups 3
PDFs 120
Videos 25 distinct / 28 raw rows

Metadata Fields

Column Description
Title Record title from the release table
Agency Source agency or collection label
Release Date Release date for the public file set
Incident Date Date associated with the underlying incident, if present
Incident Location Location associated with the underlying incident, if present
`PDF Image Link`
Type Source file type label
Document Link Canonical link used in the local mirror
Source Filename Sanitized source filename
File Group Normalized storage group, such as PDF, VID, or IMG
Output Path Relative path to the mirrored file

Notes

  • The source release contains 162 metadata rows, but two video items are duplicated, leaving 159 distinct documents.
  • metadata.csv and metadata.parquet are deduplicated on Output Path.
  • metadata_raw.csv preserves the exact exported table before deduplication.
  • Missingness is concentrated in Incident Date and Incident 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.
