FBI UFO FILES

THE 62-HQ-83894 CASE FILE

At the center of the bureau's UFO holdings sits file 62-HQ-83894 — the FBI's primary "flying disc" case file, opened in the late 1940s and worked across roughly two decades. Umbra carries it as a ten-section file with numerous individual serials threaded through it: Serial 130, 153, 164, 220, 403, 438, 449, and more, each a separately filed memorandum, report, or correspondence. The span runs from 1947 into 1968, covering the years when the bureau fielded a steady traffic of disc reports — including the era of the 1950 Guy Hottel memo, the most-requested document the bureau has ever released on the subject.

FIELD REPORTS & WITNESS INTERVIEWS

Beyond the headquarters file, Umbra indexes field-office case material under the bureau's 100-DE classification — items such as 100-DE-18221 Serial 844 and 100-DE-26505, the working paper of a regional office. Two interview records stand out. A 1958 memo logs a UFO sighting reported by a Detroit man. A 1957 report captures the bureau's interview with Wladyslaw Krasuski, who recounted watching a large circular vehicle rise vertically near a German military compound in 1944 — a wartime account filed years after the fact, preserved verbatim in the record.

PHOTOGRAPHS & LAB ANALYSIS

The collection includes photographs the bureau gathered and processed — released under PURSUE as plates such as "FBI Photo A1-8." One image pairs an actual site photograph with an FBI-Lab-rendered graphic overlay, reconstructing corroborating eyewitness reports from September 2023 of an ellipsoid bronze metallic object that materialized out of a bright light, measured 130 to 195 feet long, and vanished instantaneously. Umbra presents these plates full-frame, with their bureau markings intact, so you read the photograph and the lab's annotation together as they were filed.

The full set — case file, serials, field reports, and photographs — lives in the app. Download Umbra to page through the bureau's UFO record on your iPhone, search every serial, and keep the archive in your pocket offline.
