U.S. Air Force Flying Discs File, 1952

U.S. Department of War · 1952 · 253 pages · text from the file's own layer

This 1952 file of U.S. Air Force intelligence correspondence on flying objects comes from the Directorate of Intelligence at Headquarters USAF. It records the return to the Coast Guard of a negative of objects photographed at Salem Air Station on 16 July 1952, and requests to Naval Intelligence to analyze the Tremonton film by Delbert Newhouse and the Great Falls film by Nicholas Mariana. It also holds Strategic Air Command report transmittals, letters from members of the public, and an Okinawa object said to have fallen into the sea.

From the source:Release of 2026-09-18 Incident: September - December 1952, Various. This file is an archival collection of U.S. Air Force Director of Intelligence records relating to reported “flying disc” incidents during the period from September through December 1952. Drawn from multiple governmental and non-governmental sources, it compiles a wide range of material associated with reported sightings and official handling of those observations, rather than presenting a single analytical conclusion on the nature or origin of “flying discs.” The contents include correspondence, memoranda, reporting forms, case summaries, distribution and routing material, and other administrative or intelligence-related documentation tied to flying-disc reporting and review during that period. Pages 26-36 of the file refer to an incident reported near Tremonton, Utah, in July 1952, in which a U.S. Navy Warrant Officer recorded film of unidentified objects that the Air Force later assessed were likely seabirds. Overall, the file is a broad documentary collection reflecting how such reports were recorded, circulated, and evaluated in late 1952.

DOW-UAP-PR159 · video · 1952-07-02 Historical Film of Reported UFOs, Utah, 1952 This archival footage is a digitization of a 16mm print of Kodachrome color motion-picture film shot on a handheld Bell & Howell Auto Master camera near Tremonton, Utah, on July 2, 1952. U.S. Navy Chief Warrant Officer Delbert C. Newhouse reported observing and filming a group of bright airborne objects and shortly thereafter submitted the footage to the U.S. Air Force. The film later became one of the visual cases reviewed by Project Blue Book, the 1952–1969 U.S. Air Force program that investigated the nature and origin of unidentified flying objects (UFOs). The film’s limited detail and lack of fixed reference points prevented a conclusive resolution. From the 55-second mark onward, the film transitions to unrelated footage appearing to show a demonstration of sewing equipment. The presence of unrelated sewing-equipment footage suggests that the surviving footage may be a composite or reused print, though the available record does not establish how or when the materials came to be combined. As documented in records submitted with the film, contained in this collection under the title DOW-UAP-D102, the footage originally was paired with mountain scenery from Idaho, which is not preserved in this digitization.

I 1hould like to preaeut to y011 "hat r believe to
be a tenable theoey as to the origin and nature ot the
pllenomen.a popularly kno"D as •n11~ 68.ucersn .
•
It bas been ai:tpl;r daonatrated that electr~mgnetlc
radiation of sufficient power densi\7 is capable of
ionizing gas at low pressure. Upon deion1sat1on. the
t,11a emits radiation ot eharacteriatic waTe lengths._ come
ot i.hieh lie in the Tisible spectrma. Jlnrther. it 1a
known that radar equipment can detect ionised gaa, such••
northern lights. or charged wahr droplets . such aa ap:pear
in thunderclouda.
I belieTe that ionization of diao-shaped aegcienta of
air 1n the upper atmosphere u7 be cauaed w beaJBI from a r
radar transaitter held in a flied position or slovl7 traYeraed.
instead of the uaual aweepin« Jllotion.
!o ver1f7 the possibility. I propose in the Ter7 near
future to conduct an experiment . .6. glass sphere containing
air at atmoSJ-'here pressure will be erposed to radiation of a
kn.ow wave length and power denait7. !he pressure in the
aphere vill then be reduced until: 1on1zaUon. occurs. !he
screen of a separate radar transmitter- receiver will also
be obserTed to note vl:iether the change in the eon.ditton ot
the air is detectable b,- ractu,-. •
