Fourth Air Force Saucer File, 1949: A Cowlitz River Sketch and Clippings
The Fourth Air Force's 1949 UFO file from Hamilton: Air Intelligence Information Reports, a witness sketch of an object near the Cowlitz River in Washington, and clippings from Oakland, Colorado and Utah.
What this record is
This is the 1949 volume of the Fourth Air Force’s file of correspondence about unidentified flying objects, kept at Hamilton, north of San Francisco. It is 115 pages long. The catalog gives the Fourth Air Force as originator and its Office of Information as recipient. The file was classified SECRET, exists only on microfilm, and was declassified in full by the Air Force Declassification Office on May 22, 2025. Like its 1947 and 1952 companions, it was transferred to the National Archives because its subject is UFO reports. One oddity: the pages carry the microfilm number 01030306, which is the number of the 1947 volume, rather than a number of their own.
Very little of it can be read by machine. Only about a dozen pages returned usable OCR text, and most of those show only a form heading. The rest are faint carbons, handwriting or blank microfilm frames. Page numbers here are those of the PDF.
What it says about UFOs
The whole file concerns UFOs, but the legible substance is thin. Five pages (80, 89, 90, 96 and 103) are headed “Air Intelligence Information Report”, the standard Air Force intelligence form of the period, and page 108 is headed “Summary of Information”. The bodies of these reports did not survive OCR, so the sightings they describe can’t be reported from the text.
The most informative page is a hand-drawn witness sketch on page 85. It is dated a “3” of 1949, and the month is garbled in the OCR. Its labels mention three simultaneous witnesses, skywriting, a height figure of 70,000 feet, the Cowlitz River, an airport, smoke that “curved in wind” while “ascending,” an object “lost behind” something, and a scale of approximately one mile. The Cowlitz runs through Longview, Washington, and published catalogs record a sighting there on July 3, 1949, when the airport manager, Moulton B. Taylor, announced a disc to an air show crowd over the public address system. The sketch fits that event well. However, the town and the month can’t be read on the page, so the match is an inference.
The remaining legible pages are newspaper clippings. “Oaklander Sees Six Flying Saucers Go Over—Square Ones” appears on page 92. Page 98 carries “Fragments Believed Parts of ‘Flying Discs’ Found,” with the subhead “Metal Objects Discovered in Colorado Taken Over by Investigators for U.S. Air Force.” Page 100 holds a fragment of a headline about something “Seen in North Utah.” The article texts are not legible.
Context
In 1949 the Air Force’s central study of flying saucer reports was Project Grudge at Wright-Patterson Air Force Base, which had replaced Project Sign early that year and took a much more dismissive line. Regional commands like the Fourth Air Force collected reports on the Air Intelligence Information Report form and passed them up the chain. For the program that came before, see the Project Sign progress report, and for the long view, the history of Project Blue Book.
Status
This record proves that the Fourth Air Force was still receiving and filing UFO reports in 1949, on the standard intelligence form, and clipping the press as it had in 1947. It doesn’t tell us what any witness saw, because the report bodies are unreadable in the OCR, and the clippings are newspaper claims rather than findings. The Cowlitz River sketch is the one piece of first-hand witness material that survives, and even that is only labels and lines. Anyone wanting more will have to go to the microfilm images in the PDF.
