A quick guide to finding files, filtering by release and downloading records from the Department of War's UFO portal.
Everything in the PURSUE program is free and public at WAR.GOV/UFO, no security clearance required.
Browse by release
The site lets you filter by release. For example, this link shows only the second release.
Read the file IDs
Each case has an identifier. DoW-UAP-D plus a number is the mission report ID, and PR plus a number is the sequential ID on the site's slideshow.
Download in bulk
Some releases are available as a single archive, like the fourth release. A machine-readable index is also posted for researchers.
