Document Archive
Evidence Room
The Evidence Room is the master catalog of every primary source document processed by Unresolved Signals. Every claim in every episode traces back to a specific document in this archive, identified by name, origin, date, and provenance tier. Each source is tagged with the episode(s) that cite it.
As the show's corpus grows, this catalog will become searchable by country, decade, source type, tier rating, and entity name. The goal: every finding the show presents can be independently verified by the audience using the same source material.
Source Tier System
Tier 1 — Government Primary Documents
Official government and military records, congressional testimony, court filings, declassified intelligence reports. Highest provenance confidence.
Tier 2 — Verified Historical and Journalistic Sources
Published academic research, established news organizations' investigative reporting, verified historical documents with clear provenance chains.
Tier 3 — Contested or Limited Corroboration
Sources with disputed provenance, single-witness accounts without independent corroboration, documents whose authenticity is debated by researchers. Included when relevant but flagged accordingly.

Edward J. Ruppelt, "The Report on Unidentified Flying Objects" (Doubleday, 1956; revised edition 1960)
EP 08 EP 06 EP 05Primary source for Project Sign operations, the Estimate of the Situation, Vandenberg's rejection, the transition to Project Grudge, the Fort Monmouth overhaul, Project Blue Book's establishment, the Lubbock Lights investigation, and the 1952 Washington D.C. sightings. Ruppelt was the first director of Project Blue Book, coined the term "UFO," and provides the most detailed insider account of this period. The 1960 revised edition added three chapters reversing Ruppelt's earlier position; his widow later attributed the reversal to pressure from his former superiors. Ruppelt died of a second heart attack twelve months after the revised edition at age 37. Critical caveat on the Estimate: single source for its existence and destruction.

Published six years after the 1966 swamp-gas press conference as Hynek's public break with the Air Force debunking regime.
