PURSUE Record — FBI 62-HQ-83894 — Dewayne Johnson Ucla Dissertation Arnold Second Pass 1950: Federal Bureau of Investigation · United States — case-specific (se

FBI file 62-HQ-83894 is a single-part declassified PDF released by the Federal Bureau of Investigation as part of PURSUE Release 01 on May 8, 2026. Its internal case slug — dewayne-johnson-ucla-dissertation-arnold-second-pass-1950 — encodes a specific analytical lineage: material from 1950 connected to academic work at UCLA and what the Bureau indexed as a renewed pass at the Kenneth Arnold sighting, the June 1947 incident that introduced the phrase "flying saucers" into the public vocabulary. This document is a record of that institutional paper trail, not a new sighting report.

What this record contains

The releasing agency is the Federal Bureau of Investigation, and the document date is 1950. The file is a single-part PDF drawn from the FBI's long-running flying-discs case series — a collection the Bureau maintained from 1944 through 1973. The public release inventory describes it as "FBI 62-HQ-83894 case file material covering the case identified internally by the slug 'dewayne-johnson-ucla-dissertation-arnold-second-pass-1950,'" and explicitly notes that case-specific metadata is sparse. Beyond the slug semantics, the releasing agency's institutional posture during the period, and the 1950 date, the public inventory does not supply witness accounts, geographic coordinates, or a detailed incident description. What the slug does suggest is that the file documents Bureau engagement with academic research — a UCLA dissertation associated with the name Dewayne Johnson — specifically revisiting the Arnold case roughly three years after it occurred.

The phrase "second pass" in the slug is worth noting carefully: it implies this is not primary witness testimony but rather a secondary analytical or documentary effort. Whether the FBI was reviewing, responding to, or simply filing the dissertation material is not determinable from the metadata alone.

Historical & documentary context

By 1950, the FBI was three years into what would become one of its more bureaucratically ambiguous roles in early UAP history. Following J. Edgar Hoover's 1947 agreement — and subsequent friction — with Army Air Forces intelligence over shared access to recovered material, the Bureau occupied an uneasy position: officially out of the flying-saucer investigation business by late 1947, yet continuing to file and receive reports through field offices well into the 1950s. The Kenneth Arnold sighting of June 24, 1947, near Mount Rainier, Washington, was the ignition point for that entire institutional response. Arnold reported nine crescent-shaped objects traveling at speeds no known aircraft of the era could match; press coverage transformed his description into "flying saucers," and the phrase became global within days. A UCLA dissertation revisiting that case in 1950 would have been entering an already politically charged space, and Bureau attention to such academic work — even if only archival — is consistent with the FBI's documented practice of monitoring civilian research touching national-security-adjacent topics during the early Cold War.

What this does and does not prove

The documented facts here are narrow: a PDF exists, it carries case number 62-HQ-83894, the Bureau assigned it a slug connecting it to a UCLA dissertation and to Arnold's 1947 sighting, and it was filed sometime around 1950. Nothing in the public metadata confirms the dissertation's conclusions, establishes what the Bureau's response to that research was, or characterizes what Dewayne Johnson argued. The release inventory does not include a summary of the file's substantive content. Treating this record as evidence of any particular explanation for the Arnold sighting — in either direction — would go beyond what the document, as publicly described, supports. It is evidence that the FBI was tracking academic engagement with the Arnold case in 1950. That is the full extent of what can be responsibly stated.

How it fits PURSUE Release 01

This file belongs to the FBI flying-discs archive strand of PURSUE Release 01 — the subset of the May 8, 2026 Department of War release drawn from Bureau case files spanning 1944 to 1973. The 120-PDF component of the 162-document release leans heavily on this historical FBI corpus alongside DoW mission reports and NASA archive imagery, and records like 62-HQ-83894 illustrate the analytical discipline the release is meant to model: including documents whose metadata is thin, whose contents are secondary or administrative, and whose connection to any unresolved aerial phenomenon is indirect.
