FOIA & The Black Vault: How to Read Docs

If you study UAP seriously, your best “sensors” are often declassified records, FOIA releases, and agency reading rooms. But getting value from those documents takes more than skimming headlines. This guide teaches a data-first approach to Freedom of Information Act (FOIA) material and third-party repositories like The Black Vault, so you can authenticate sources, decode markings, avoid common traps, and build defensible claims that stand up to scrutiny.

We’ll cover FOIA basics, the mechanics of authentication, pitfalls (and how to dodge them), and we’ll end with a curated library of active links to core resources you’ll use every week.

FOIA: the must-knows. 

  • FOIA gives you a right of access to federal agency records, subject to nine exemptions and three exclusions. FOIA.gov provides the plain-language starting point and FAQ for requesters. (FOIA.gov)
  • Timelines: Agencies generally must make a determination within 20 working days (with limited extensions for “unusual circumstances”). Your appeal window is at least 90 days after an adverse determination. (FOIA.gov, Department of Justice)
  • Presumption of openness / foreseeable harm: Since the FOIA Improvement Act of 2016, agencies should not withhold unless they reasonably foresee harm to an interest protected by an exemption. This is now baked into policy guidance. (Department of Justice)
  • Mediation: If you hit a wall, the Office of Government Information Services (OGIS) provides free dispute resolution between you and agencies. (National Archives)
  • “Glomar” / NCND: An agency may neither confirm nor deny records only when paired with a valid exemption (commonly Exemption 1 or 3). OIP and OGIS explain this clearly. (Department of Justice, National Archives)

For UAP researchers, these points matter because they define what you can get, how long it should take, and the lanes agencies use to withhold or confirm.

FOIA Exemptions that matter most in UAP work, and how to read them

You will see exemption codes in cover letters and page footers (e.g., “(b)(1)”, “(b)(3)”, “(b)(5)”). Here’s how to interpret the heavy hitters:

  • Exemption (b)(1): Properly classified national security info. If a page is withheld under (b)(1), ask whether a segregable portion can be released; the foreseeable-harm test still applies. (FOIA.gov)
  • Exemption (b)(3): Withheld under other statutes – a frequent brick wall for UAP work. Key example: 50 U.S.C. § 3024(i) (DNI’s duty to protect intelligence sources and methods). When you see (b)(3)/50 USC 3024(i) in a margin, you’re up against a specific law, not agency discretion. (Department of Justice, Legal Information Institute, open.defense.gov)
  • Exemption (b)(5): Deliberative Process and related privileges. After 2016, agencies must also articulate foreseeable harm from release; DOJ has refined guidance post-Sierra Club. Don’t overread (b)(5): it covers pre-decisional deliberations, not final working law or operative policy. (Department of Justice)
  • Exclusions (552(c)): Rare “law-enforcement sensitive” carve-outs where agencies may exclude records from FOIA processing entirely. Understand these exist, but don’t default to assuming them. (Department of Justice)

The Black Vault: what it is, and how to use it professionally

The Black Vault is a long-running, public FOIA archive created by John Greenewald, Jr. It hosts millions of pages obtained via FOIA or proactive disclosure, including agency letters, logs, and UAP-titled records. Treat it as a finding aid and mirror; whenever possible, triangulate documents against official reading rooms. (theblackvault.com)

Two practical anchors you can cite when validating Black Vault materials:

  • Official DoD confirmation of Navy UAP videos (2020): DoD publicly released three Navy videos and pointed to the NAVAIR FOIA reading room. That’s the kind of government-hosted link you want to match with any third-party mirror. (U.S. Department of Defense, Naval Air Systems Command)
  • FOIA letters to Greenewald (examples): Black Vault often posts the original agency letters with FOIA case numbers, dates, and signatures — e.g., OSD responses to Greenewald in 2025. These are primary artifacts that help authenticate a release. (documents2.theblackvault.com)

Best practice: When you cite a document hosted at The Black Vault, also cite the matching agency source (if it exists) or at least the agency cover letter that transmitted it.

Workflow for reading FOIA/UAP documents

Think like an analyst: provenance → structure → markings → content → claims.

1) Establish provenance

  1. Who created the record? (letterhead, component, office symbol)
  2. How did it arrive? (FOIA case number, cover letter, date, signer)
  3. Where else is it hosted? (agency reading room or FOIA portal)

Tools & tells:

2) Inventory the packet

  • Bates/page numbers: Note “Page X of Y,” missing sequences, duplicated pages.
  • Release posture per page: Release in full vs release in part vs withheld. Track by page to see what’s consistently redacted and under which exemption(s).
  • Referral chains: Indicators that a page originated with another component (watch for referral/consultation notes), which can explain delays and mixed markings. (Department of Justice)

3) Decode markings and headers/footers

  • Classification banners (“UNCLASSIFIED”, “SECRET”) and portion markings.
  • CUI banners and designation indicator blocks (CUI category, controlling office, LDC/REL TO). CUI replaced legacy caveats like FOUO and SBU; know what proper CUI looks like so you can tell modern from legacy scans. (WHS ESD, dodcui.mil)
  • Distribution statements (DoDI 5230.24): A through F (e.g., “Distribution Statement A. Approved for public release: distribution is unlimited.”). Dist statements regulate dissemination of technical information and do not automatically mean a document is CUI. (WHS ESD, dodcui.mil)

4) Map redactions to law

Create a table: page → (b)(X) → statute (if b(3)) → foreseeable harm statement?
Use DOJ’s Exemption 3 guide to identify the exact statute when redaction callouts cite legal codes. For UAP cases, 50 U.S.C. § 3024(i) appears frequently. (Department of Justice, Legal Information Institute)

5) Cross-validate content claims

Examples

A) Navy UAP videos (2004/2015) — authenticating via official sources

  • DoD press release (2020) confirms the videos and points explicitly to the NAVAIR FOIA Reading Room for the official copies. That public confirmation plus a government-hosted source is gold-standard provenance. (U.S. Department of Defense)
  • If you see the same files mirrored on The Black Vault or in media, cite both: the official DoD/NAVAIR link for authenticity and the accessible mirror for reader convenience. (Naval Air Systems Command)

B) DIA FOIA — medical/physiological effects and AAWSAP-era papers

  • The DIA FOIA reading room hosts AAWSAP-related material (e.g., medical effects paper). These documents often carry distribution statements and may reference legacy UAP terminology in the body text. Validate with the official file first. (Defense Intelligence Agency)
  • When a Black Vault posting claims DIA released X documents in response to request Y, look for matching entries in DIA FOIA logs and confirm the number and dates. (Defense Intelligence Agency)

C) ODNI/AARO UAP reporting — triangulating government narratives

Common pitfalls (and fixes)

  • Pitfall: “No records” means nothing exists.
    Often it means “no records located in this component” or “no records matching your description.” Narrowing scope or routing to the correct component yields better results; referrals/consultations are common in multi-agency equities. (Department of Justice)
  • Pitfall: Equating distribution statements with CUI/classification.
    Distribution Statement A–F governs dissemination of technical information and is separate from classification and CUI status. Do not infer classification from a distribution statement alone. (WHS ESD, dodcui.mil)
  • Pitfall: Overreading (b)(5).
    Deliberative process shields pre-decisional discussions, not final policy. Post-2016, agencies must still show foreseeable harm to withhold. Check if the cited harm is specific, not boilerplate. (Department of Justice)
  • Pitfall: Treating third-party mirrors as primary.
    Always tie a mirror to an agency-hosted source or the agency’s cover letter. This is crucial for provenance, chain-of-custody, and citation integrity. (documents2.theblackvault.com)
  • Pitfall: Ignoring proactive disclosures.
    Before filing, search FOIA reading rooms (FBI Vault, CIA Reading Room, ODNI, AARO). If it’s already public, cite the official version. (FBI, CIA, AARO)
  • Pitfall: Fee shocks and delays.
    Know your fee category (news media, educational, all other, commercial), request a fee waiver when appropriate, and note that missed time limits can limit fee assessments under DOJ guidance. (FOIA.gov, Legal Information Institute, Department of Justice)

Reading what the markings really say

Classification & Portions

Government records may have portion markings (e.g., (U), (C), (S)) per paragraph/figure. Lack of portion markings on old scans doesn’t mean text is unclassified; it may simply reflect older practice or poor reproduction.

CUI (Controlled Unclassified Information)

Modern unclassified yet controlled materials (e.g., certain tech data, privacy info) should show CUI in the banner with a designation block (category, controlling office, LDC). If you see legacy FOUO/SBU, you’re likely dealing with pre-CUI artifacts or non-updated templates. (WHS ESD, National Archives, dodcui.mil)

Distribution Statements

For technical documents, DoDI 5230.24 governs distribution statements. The phrase you most want to see is “Distribution A. Approved for public release: distribution is unlimited.” Anything else implies constraints that should be respected in redistribution. (WHS ESD)

Building claims from FOIA docs

UAP Wiki distinguishes between evidence and interpretation. When your analysis leans on FOIA-sourced material:

  1. Extract facts that are explicitly in the document (who/what/when/where, counts, dates, sensor types).
  2. Tie facts to citations (agency PDFs, FOIA letters, reading room links).
  3. Label interpretations clearly (see Speculation labels below).
  4. Classify the overall claim using the sourcing & claims taxonomy (below).

Example: “The Department of Defense confirmed three Navy UAP videos and hosted them via the NAVAIR FOIA Reading Room.” That is a verified factual statement with direct government sources. (U.S. Department of Defense)

Practical FOIA How-to

  1. Search before you file. Hit FOIA.gov, agency reading rooms, and AARO/ODNI first. (FOIA.gov, FBI, AARO)
  2. Reasonably describe records. Specify time windows, program elements (e.g., “AARO, ODNI UAP office, NAVAIR safety reports”), and record types (emails with subject “UAP,” logs, videos, message traffic). (FOIA.gov)
  3. Pick the right component. Navy safety center ≠ NAVAIR ≠ ONR; ODNI ≠ individual IC elements. When in doubt, submit to the component most likely to be the record owner.
  4. Fees & category. Identify yourself as news media/educational if eligible; request fee waiver when contributing to public understanding; remember the time-limit fee restrictions guidance. (FOIA.gov, Legal Information Institute, Department of Justice)
  5. Escalate smartly. If delayed or denied, appeal within 90 days and consider OGIS mediation. Cite the foreseeable harm standard where appropriate. (Department of Justice, National Archives)

Implications for UAP research & policy

  • Raising the floor on evidence quality. FOIA has matured: foreseeable harm, 90-day appeals, and growing proactive disclosures mean the documentary baseline for UAP studies is stronger than a decade ago. (Department of Justice)
  • Sharper boundaries on what stays hidden. Exemption (b)(3) statutes (e.g., 50 U.S.C. § 3024(i)) create hard stops around sources/methods. Expect structured releases that discuss phenomena while masking collection. Build analyses that respect those boundaries while still extracting useful signal. (Legal Information Institute)
  • Triangulation as standard practice. With AARO, ODNI, and service-component reading rooms publishing overlapping materials, high-quality UAP research now triangulates across agencies, not just headlines. (AARO, Director of National Intelligence)
  • The Black Vault as a force multiplier. Treat it as a catalog and amplifier — invaluable for discovery and historical continuity — but ground your conclusions in agency-hosted sources and FOIA letters. (theblackvault.com)
