The release calls it “DAF Committee to Review Project Bluebook, 1966-1967”. Release filename only, and it describes the file inexactly: the file holds records of the USAF Scientific Advisory Board ad hoc committee (1966) AND of the University of Colorado (Condon) study (1967). No single title page covers it. It is not adopted as a title here.

rendered and read by eye — the grade this project quotes fromCaveat AARO DOES NOT USE THE WORD "FIRST" OR THE WORD "DIRECTOR" HERE. It says Blue Book "was led successively by" five officers and lists Ruppelt at the head of that list, having previously directed the reorganised Project GRUDGE.

The claim we testedorigin of secrecy narrativeWhat the document actually saysRoswell, for example, is not referred to in the official USAF investigation of UFOs reported in Project Bluebook or its predecessors, Project Sign and Project Grudge, which ran from 1948-1969.Report of Air Force Research Regarding the "Roswell Incident", 1994
printed p. 13 · read off the page footerWhy we refused it. THE ONLY PRIMARY THIS PROJECT HOLDS ON THIS PAIR SAYS THE CASE IS ABSENT FROM BLUE BOOK. Printed 11 records the same thing from the other direction: Congressman Schiff was told Roswell was part of Blue Book, asked the National Archives, and was told it was not. A link asserting Roswell as the origin of a Blue Book secrecy narrative cannot be bound to a document that says Blue Book never held the case. The link is left standing on its own citation, and this refusal is the note that the nearest primary cuts against it. -
reviewed its case files and found no evidence of craftWhy we refused it. NOT BOUND - THE DOCUMENT NAMES ATIC, NOT BLUE BOOK. TAB A says the Panel "has received the evidence as presented by cognizant intelligence agencies, primarily the Air Technical Intelligence Center, and has reviewed a selection of the best documented incidents". Blue Book was ATIC's project, and reading one as the other is a step this document does not take and this project does not take for it.

Donald F. Chamberlain, Assistant Director of OSI, subsequently informed McCone that little had changed since the early 1950s.Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena (UAP), Volume I, 2024
printed p. 19 · read off the page footerWhy we refused it. THE SECOND PAGE IN THIS DOCUMENT THAT NAMES A DIFFERENT MAN. Printed 17 attributes the 1953 panel to Chadwell under DCI Walter Bedell Smith; printed 19 attributes the 1964 re-evaluation to DCI John McCone through Chamberlain. Dulles is named on neither. TWO SEPARATE CIA REVIEWS OF UFO WORK, TWO NAMED DIRECTORS OF CENTRAL INTELLIGENCE, NEITHER OF THEM DULLES. Taken with the refusal on link 394, this map has two links putting Dulles at the centre of CIA UFO oversight and no document that puts him there. -

3 corrections to this record
Generated from the record, not written by hand. Every change keeps what the map used to say, because a correction nobody can see is indistinguishable from never having been wrong.
Project Blue Book → Invasion of Washington (1952)
investigated it and attributed it to temperature inversions
the official explanation attributed it to a low-level temperature inversion
Printed 71 names the inversion explicitly but attributes it to "the official explanation" and "the official suggestion". It never says Blue Book. The edge still connects the event to Blue Book; the relation no longer claims the page said so.
Project Blue Book → James E. McDonald
worked from its case files at Wright-Patterson
visited Wright-Patterson Air Force Base and examined its UFO files
Printed 19 says he visited and saw the files. It says Wright-Patterson, not Blue Book, and seeing is not working from.
Project Blue Book → 4602nd Air Intelligence Service Squadron
took over field investigation of UFO reports for it under AFR 200-2
held the UFO case files, 1954-1956, in the Air Force investigation chain
The NARA series record proves the 4602d held UFO case files in RG 341 for 1954-1956 and places the squadron in the Air Force UFO chain of custody. AFR 200-2 has never been read by this project; it was asserted from a citation line. Removed rather than left reading as sourced. It can return the day someone opens the regulation. Note also that this source is a NARA SERIES, and whether a series counts as a document is still an open question here. Operator decision, 2026-08-21.
