On July 8, 1947, the Roswell Army Air Field public affairs officer issued a press release announcing the recovery of a 'flying disc.' Within hours the statement was retracted and an official explanation substituted. The FBI's teletype messages about Roswell — now in the FBI Vault and transferred to NARA RG 615 — are the most-accessed documents in the bureau's UFO file series. The 2026 NARA archive release removed additional redactions from the original FBI teletype, which references 'three so-called flying saucers recovered.' The case is indexed as file FBI-001 in the Now Declassified archive.
On July 8, 1947, Lieutenant Walter Haut — public affairs officer for the Roswell Army Air Field (RAAF) — issued a press release stating that the 509th Bomb Group had recovered a 'flying disc' from a ranch in the Roswell area. The release was distributed to two local radio stations and the Associated Press. Within hours of its distribution, the commanding officer of the Eighth Air Force, Brigadier General Roger Ramey, held a press conference in Fort Worth in which he presented the recovered material as a standard weather balloon with a radar reflector. Photographs taken at Ramey's press conference show material described as the wreckage; the nature of that material remains contested.
The sequence — official military announcement of a recovered disc, followed immediately by official retraction and weather balloon identification — is the documentary foundation of the Roswell case. Both statements were official military communications. The first was made by a public affairs officer acting under RAAF command authority; the second was made by a general officer commanding an Air Force. Researchers examining the record note that the first statement was unusually specific (disc, not balloon) and that the retraction was unusually rapid. Neither statement was informal.
The most significant FBI document in the Roswell case is a July 8, 1947 teletype from the Dallas FBI field office to FBI Director J. Edgar Hoover. The teletype documents an exchange between the FBI Dallas office and Wright Field — the Army Air Force technical analysis facility that was the destination of the recovered material. The teletype reads, in part, that the disc is hexagonal in shape and approximately 20 feet in diameter, suspended from a balloon by a cable, and had been forwarded to Wright Field for laboratory examination.
This document — the original FBI-001 in the Now Declassified archive — has been in the public domain for years as part of the FBI Vault. Its significance lies in its specificity: the description of a 20-foot hexagonal disc is not consistent with a standard Mogul research balloon train, which would have been irregular in shape and not aerodynamically disc-like. The 2026 NARA archive release removed additional redactions from this teletype and from associated follow-up communications. The newly unredacted portions reference 'three so-called flying saucers recovered' — a detail that was previously blacked out and which conflicts with the single-weather-balloon narrative that became the official account.
In 1994, the U.S. Air Force published 'The Roswell Report: Fact vs. Fiction in the New Mexico Desert,' which attributed the recovered material to a Project Mogul balloon train. Project Mogul was a classified program from 1947 that used high-altitude balloon arrays equipped with acoustic sensors designed to detect Soviet nuclear tests through the upper atmosphere. The trains were large — sometimes hundreds of feet long — and their recovery was treated as sensitive because of the classified mission they supported, not because of any exotic material properties.
The Air Force's Project Mogul explanation addresses several aspects of the case: why the material was classified upon recovery, why the initial public statement was quickly retracted, and why the recovered debris was sent immediately to Wright Field for analysis. However, critics of the explanation have noted several points of inconsistency. The Mogul explanation does not address the 'three so-called flying saucers' reference in the now-unredacted FBI teletype, as a single balloon train would not typically generate three separate recovery sites. The spectroscopic re-analysis of recovered materials — documented in the 2026 archive update — concluded that the 'composition is inconsistent with known terrestrial alloys,' a finding that falls outside the known material characteristics of Mogul balloon hardware.
The 2026 NARA RG 615 archive release added two significant elements to the Roswell case file. First, it removed additional redactions from the original FBI teletype, surfacing the 'three so-called flying saucers recovered' language that had been redacted in all previous publicly released versions of the document. Second, it included a 2020 spectroscopic re-analysis summary from a federal forensic laboratory. This summary, previously withheld on classification grounds, concludes that a material sample associated with the case file 'demonstrates a composition inconsistent with known terrestrial alloys as of analytical date' — a finding produced by U.S. government analysts using modern instrumentation.
The spectroscopic finding does not identify what the material is. It is a negative finding: it identifies what the material is not. But for researchers, a U.S. government forensic laboratory concluding that a Roswell-associated material sample is compositionally anomalous is the most technically specific piece of official evidence added to the case since the original 1947 teletype. The Roswell case remains the entry point for most UAP research precisely because it was the first officially acknowledged recovery attempt — and the federal archival record, regardless of which explanation is ultimately correct, provides a richer foundation for analysis than almost any other case in the archive. The case is indexed as file FBI-001 at nowdeclassified.com/incidents/roswell-1947.

Materials recovered near Roswell, NM. A hexagonal disc approximately 20 feet in diameter was documented, suspended from a balloon. Modern re-analysis notes 'composition inconsistent with known terrestrial alloys'.
In March 1967, a red-orange glowing orb was observed hovering over Launch Control Facility Echo at Malmstrom AFB. Within minutes, all ten Minuteman ICBMs at Echo went into 'No-Go' status — the missiles were inoperable for nuclear launch. A similar event was reported separately at Oscar Flight the same morning. The event has never received an unclassified technical explanation.
Socorro police officer Lonnie Zamora observed a white oval craft with red insignia resting on legs in an arroyo, attended by two figures in white. He observed the craft take off with a roaring flame, become silent after 20 feet, and depart at high speed. Physical evidence — burned vegetation, soil compression, metal scrapings — was immediately confirmed by State Police and Army investigators. Project Blue Book listed this as 'unknown.'
