Air Force Report Came With a CIA Cover
The cover is stamped “Official Copy.” A handwritten note appears on the first page, but the summary doesn’t say what it reads.

A US Air Force report came with a CIA cover. The summary mentions a handwritten note on the first page but doesn’t reveal what it says.
This is Project Blue Book Special Report No. 14 (Project No. 10073), 'Analysis of Reports of Unidentified Aerial Objects,' dated 5 May 1955, produced by the Air Technical Intelligence Center at Wright-Patterson Air Force Base, Ohio, here circulated with a CIA 'Official Record Copy' cover sheet. It is a statistical study in which roughly 4,000 UFO sighting reports received by the U.S. Air Force between mid-1947 and the end of 1952 were reduced to IBM punched-card abstracts, categorized (Balloon, Aircraft, Astronomical, Other, Insufficient Information, Unknown), graphed, and subjected to chi-square tests comparing 'knowns' against 'unknowns.' The report concludes it is highly improbable that any of the reports represent technological developments outside present-day scientific knowledge and emphasizes the complete lack of valid physical evidence in any case.
Kenneth Arnold publicly reported the now-famous sighting of a chainlike formation of disc-shaped objects; resulting newspaper publicity spawned the term 'flying saucers' and a wave of subsequent reports.
"Therefore, on the basis of this evaluation of the information, it is considered to be highly improbable that reports of unidentified aerial objects examined in this study represent observations of technological developments outside of the range of present-day scientific knowledge. It is emphasized that there has been a complete lack of any valid evidence of physical matter in any case of a reported unidentified aerial object."
Why it matters: The central conclusion of the study and one of the most-cited Air Force statements on UFOs.

"any aerial phenomenon or sighting that remains unexplained to the viewer at least long enough for him to write a report about it"
Speaker: Dr. J. Allen Hynek
Why it matters: Hynek's cited working definition of a 'flying saucer' adopted to frame the study.

"any conclusions contained in this report are based NOT on facts, but on what many observers thought and estimated the true facts to be."
Why it matters: Explicit caveat about the subjective nature of the underlying data.

Famous 1955 ATIC statistical study (Blue Book Special Report No. 14). The CIA copy adds an 'Official Record Copy' cover sheet and, per the manifest, a handwritten note on the first page; otherwise the content has long been public. Page numbers refer to the PDF scan sequence, not the report's internal Roman/Arabic pagination.
The summary describes it as a US Air Force report belonging to Project Blue Book.
The summary says there is a note on the first page but does not reproduce its contents.
A US Air Force document came with a cover from the Central Intelligence Agency, or CIA. The cover identifies it as an “Official Copy.” The official summary also explicitly mentions a handwritten note on the first page.
The document is part of Project Blue Book, an Air Force project that examined reports of unidentified things seen in the sky. But the summary says little about the report itself. It points to a small, concrete detail without revealing what the note says.
The document is titled “Special Report 14.” It analyzes reports of unidentified objects in the sky. The report belongs to the Air Force; the CIA is connected to it through the cover.
The cover is stamped “Official Copy.” That wording describes the copy, but the summary does not say the CIA wrote the report. It’s easy to conflate the two details: the report belongs to an Air Force project, while the cover is from the intelligence agency.
According to the summary, the document’s contents were already available on the CIA’s public website, except for the handwritten note on the first page. The summary neither reproduces the note nor says whether it adds information to the report or merely remarks on the document.
It also offers no example of a sighting or finding from the report. So it gives no indication of what people said they saw or what the report’s analysis concluded. The title promises a special report, but the only detail the summary singles out is the note.
The summary does not reveal what the note says or detail the report’s findings. Nor does it offer an explanation for the reported phenomena; it only says the document deals with such reports.
The report was already available to read. Even so, one detail remains in the margins: a few handwritten words on the first page, which the summary does not disclose.
