John Greenewald Jr.

John Greenewald Jr. is a public-records researcher whose disclosure role centers on The Black Vault, a privately run archive of government records obtained through the Freedom of Information Act and other public-information channels.¹² The Black Vault's document archive says Greenewald began filing FOIA requests in 1996 at age 15, and its live page counter listed 3,838,797 government-document pages when this dossier was updated in May 2026.¹ Columbia Journalism Review reported in 2020 that Greenewald had operated the archive for 24 years, that it then held more than 2 million FOIA-obtained pages, and that its users downloaded roughly ten terabytes of records each month.²

  Origin of the Archive

Greenewald's first documented FOIA path began with a September 1976 Tehran UFO-related record that he found through the Computer UFO Network while using America Online as a teenager.² Columbia Journalism Review reported that Greenewald mailed an August 11, 1996 FOIA request to the Defense Intelligence Agency for that Tehran record, received a matching DIA response about two weeks later, and treated the result as proof that the document was a real government memo rather than proof that the underlying sighting account was true.² Greenewald then reused the request as a template for additional FOIA filings and began building an online repository because he saw no comparable public archive for government documents collected through FOIA.²

The early site was first called John's World, used limited free web hosting, and required Greenewald to type mailed records by hand before a supporter helped him buy a flatbed scanner.² Columbia Journalism Review reported that the site became The Black Vault after about a year, with the new name meant to evoke vaults of information and blacked-out redactions.²

  FOIA Practice

FOIA gives any person the right to request executive-branch records from the U.S. government, while allowing agencies to withhold information that falls under nine statutory exemptions.³ Greenewald's work is therefore strongest as a record-production practice: he files requests, obtains release letters, posts records, tracks redactions, appeals denials, and preserves agency explanations of what was searched, released, or withheld.²³⁴ Columbia Journalism Review described Greenewald as a rule-following requester rather than a back-channel recipient of classified leaks, and quoted him saying he would not publish a document if there were signs it remained classified.²

  The Black Vault Record

The Black Vault describes its FOIA Document Archive as a privately run repository whose pages, photos, and videos were obtained through FOIA or other means of accessing U.S. government public information.¹ That status makes the archive useful for researchers because it often stores both the responsive records and the correspondence that explains the agency's processing decision.¹²⁴ It also means the archive is not an official government reading room: the source record may originate with an agency, while the indexing, framing, OCR, and selection usually come from Greenewald's publication work.¹²⁵

The Black Vault's CIA UFO collection illustrates both the value and the limits of that model.⁵ Greenewald's 2021 collection page says The Black Vault's effort to obtain CIA UFO records went back to 1996, describes a mid-2020 CIA CD-ROM purchase, identifies the 2,780-page data set as FOIA case F-2020-02272, and provides both original CD-ROM files and searchable PDF conversions.⁵ The same page cautions that the CIA's claim that the CD-ROM represented its entire UFO collection could not be fully verified, and it warns that searchable PDFs created from poor photocopies are imperfect.⁵

  UAP Video Requests

Greenewald's UAP-related FOIA work became especially visible after the Department of Defense formally released three historical Navy videos on April 27, 2020.⁶ The Defense Department said the videos were one November 2004 Navy video and two January 2015 Navy videos that had circulated after unauthorized releases, and it said the aerial phenomena in the videos remained characterized as unidentified.⁶

The Black Vault then sought additional Navy videos carrying a UAP designation, filing a NAVAIR request on April 28, 2020 and later pursuing other Navy components.⁷ A September 7, 2022 Navy response to Greenewald's July 11, 2022 request said the UAP Task Force located videos but determined they contained sensitive UAP information, were classified, were exempt in full under FOIA Exemption 1, and could not be segregated for partial release.⁴ The Navy response also said releasing the information would harm national security by giving adversaries information about Department of Defense or Navy operations, vulnerabilities, or capabilities.⁴

  Historical UFO Collections

Greenewald's archive also packages older official UFO records, including Black Vault pages for Project Sign, Project Grudge, and Project Blue Book materials from the Air Force UFO-investigation era.⁸ The National Archives states that Project BLUE BOOK records were transferred to NARA custody, that the project closed in 1969, and that textual records are available for research with names of people involved in sightings excluded.⁹ The Air Force fact sheet reproduced by NARA says 12,618 sightings were reported to Project BLUE BOOK from 1947 to 1969, 701 remained unidentified, and the program found no evidence that unidentified sightings represented a national-security threat, technology beyond then-current scientific knowledge, or extraterrestrial vehicles.⁹

  Evidentiary Limits

Greenewald's public importance comes from making the document trail inspectable, not from making the documents self-interpreting.¹²⁵ A FOIA release can prove that an agency had a record, processed a request, applied exemptions, or described an event in a file, but it does not automatically prove the truth of every witness report, intelligence summary, press clipping, or agency inference inside that record.²³⁵⁴ This distinction is explicit in the CIA collection page's cautions about completeness and OCR quality, in NARA's reproduction of Project BLUE BOOK's no-extraterrestrial-evidence conclusion, and in the Navy's refusal to release additional UAP videos under national-security exemptions.⁵⁴⁹

AARO's 2024 historical report reinforces the same boundary for modern UAP claims.¹⁰ AARO said it reviewed U.S. government UAP investigatory efforts since 1945, classified and unclassified archives, about 30 interviews, and relevant controlled or special-access program channels.¹⁰ The report found no evidence that any U.S. government investigation, academic-sponsored research, or official review panel had confirmed a UAP sighting as extraterrestrial technology, and it said many unresolved cases lacked the data quality needed for confident identification.¹⁰

  Dossier Assessment

Greenewald belongs in a disclosure dossier because his work preserves primary records, agency response letters, redaction decisions, appeal histories, and search results that would otherwise remain scattered across government systems or private files.¹²⁵⁴ His strongest contribution is procedural and archival: he gives researchers a way to compare official records against public claims while keeping the limits of FOIA evidence visible.²³⁵⁹¹⁰ Claims sourced through The Black Vault should therefore distinguish between the government record itself, Greenewald's reporting around that record, and any larger interpretation that the released material may or may not support.²⁵⁴¹⁰
