What is the UAP Disclosure Act?

The UAP Disclosure Act of 2024 (Schumer-Rounds Amendment) is U.S. Senate legislation modeled on the JFK Records Act that mandates a declassification timeline for UAP records held by the federal government. Unresolved Signals covers the Act in detail, tracing its legislative history and implications for government transparency on unidentified aerial phenomena.

What was the Low Memorandum?

On August 9, 1966, three months before the Condon Committee formally began its work, the committee's coordinator Robert J. Low wrote a one-page memorandum to E. James Archer (Dean of the Graduate School) and Thurston E. Manning (Vice President for Academic Affairs) at the University of Colorado. The senior administrators had been resisting the university's acceptance of the Air Force's contract to study unidentified flying objects. The memo's central passage reads: The trick would be, I think, to describe the project so that, to the public, it would appear a totally objective study but, to the scientific community, would present the image of a group of nonbelievers trying their best to be objective but having an almost zero expectation of finding a saucer. The next sentence is the operating instruction: One way to do this would be to stress investigation, not of the physical phenomena, but rather of the people who do the observing. The full text of the memorandum, with JPEG scans of the original, is available at the National Investigations Committee on Aerial Phenomena (NICAP). The memorandum was leaked to journalist John Fuller, who published it in Look magazine in May 1968 under the headline Flying Saucer Fiasco.

What was the Portage County UFO chase of April 17, 1966?

At approximately 5:00 AM on April 17, 1966, Deputy Sheriff Dale Spaur and Patrolman Wilbur Neff of the Portage County, Ohio Sheriff's Office observed a silvery, disc-shaped object with a bright underside light hovering over their patrol cruiser. They pursued it 85 miles east, across the Ohio state line, into Pennsylvania. Patrolman Wayne Huston of East Palestine, Ohio joined the chase. Patrolman Frank Panzanella of Conway, Pennsylvania witnessed the end of the pursuit. All four officers filed signed witness statements. Five days later, Major Hector Quintanilla, the director of Project Blue Book, attributed the object to a communications satellite and the planet Venus, after a brief telephone interview with one of the four officers. J. Allen Hynek, Blue Book's scientific consultant, publicly called the conclusion absurd. Six months later, in an interview with Cleveland Plain Dealer staff writer John De Groot carried on the Associated Press wire, Officer Spaur described the personal collapse that had followed the case. The Air Force itself, on its own letterhead, in a May 17, 1966 letter from Information Officer Eugene F. Rehrer, conceded that one of the four officers had been driven off his police force by the consequences of the explanation.

What did James E. McDonald tell Congress on July 29, 1968?

Doctor James E. McDonald, senior atmospheric physicist at the University of Arizona's Institute of Atmospheric Physics, testified before the House Committee on Science and Astronautics on July 29, 1968. He was the only senior scientist of his rank in the country who would publicly say that Project Blue Book had been scientifically incompetent. His prepared statement, on the public record of the United States Congress, contained five passages that capture his case. No other problem within your jurisdiction is of comparable scientific and national importance. The scientific community as a whole won't take this problem seriously because it doesn't have scientific data. They want instrumental data. Why don't they have instrumental data? Because the scientists don't take it seriously enough to get the scientific data. Credible observers are observing relatively incredible objects. There is a real ridicule lid that has not been contrived by any group. The scientific world at large is in for a shock when it becomes aware of the astonishing nature of the UFO phenomenon. McDonald recommended what he called a pluralistic approach: multiple agencies, including NASA, the National Science Foundation, and the Office of Naval Research, rather than single-agency control.

What was the Hynek to Sleeper letter of October 7, 1968?

On October 7, 1968, J. Allen Hynek, who had served as Project Blue Book's scientific consultant for twenty years, replied to a formal request from Colonel Raymond Sleeper, commander of the Foreign Technology Division at Wright-Patterson Air Force Base. Sleeper had asked Hynek for his candid scientific assessment of the project. Hynek's reply was organized as eight numbered observations. It is reproduced in full in his 1972 book, The UFO Experience: A Scientific Inquiry. Hynek wrote that neither of Blue Book's two missions, threat assessment or scientific data gathering, was being adequately executed. He wrote that the staff was grossly inadequate in numbers and in scientific training, that the project was a closed system with no scientific dialogue with the outside world, that its statistical methods were nothing less than a travesty, and that its basic attitude and approach were illogical and unscientific. He noted that Blue Book's critics had given the project a name, the Society for the Explanation of the Uninvestigated, and that he did not disagree with it.

What was the Bolender Memorandum of October 20, 1969?

On October 20, 1969, two months before Project Blue Book's public termination announcement, Brigadier General Carroll H. Rip Bolender, Deputy Director of Development and Acquisitions under the Air Force's Deputy Chief of Staff for Research and Development, wrote an internal memorandum recommending the project's termination. The memorandum also clarified, in writing, how UFO reports of national security significance were processed. The clarification was a single sentence: Reports of unidentified flying objects which could affect national security are made in accordance with JANAP 146 or Air Force Manual 55-11, and are not part of the Blue Book system. JANAP 146 (Joint Army-Navy-Air Force Publication 146, Communications Instructions for Reporting Vital Intelligence Sightings) and AFM 55-11 (the Air Force Operational Reporting System, issued in May 1968) are general operational reporting channels carrying any operationally significant report, including foreign aircraft incursions, missile launches, and suspected hostile activity. UFO reports of national security significance flowed through them because they flowed through the channels that carried any such report. What the memorandum establishes is that Project Blue Book, the public investigation that the Air Force pointed to in press statements for twenty-two years, was not the destination of UFO reports the Air Force itself considered nationally significant. Sixteen pages of attachments referenced in the memorandum are missing from the Air Force's files. They have never surfaced.

What did the 1997 CIA admission about U-2 reconnaissance reveal about Project Blue Book's unexplained cases?

In 1997, CIA historian Gerald K. Haines published an article titled CIA's Role in the Study of UFOs, 1947-90 in the Agency's internal journal Studies in Intelligence. Haines wrote that high-altitude reconnaissance flights of the U-2 (operating at 60,000 feet) and the A-12 (predecessor of the SR-71), classified above the clearance level of Project Blue Book's investigators, accounted for, in his estimate, over half of all UFO reports during the late 1950s and most of the 1960s. The estimate has been challenged by other historians as overstated. The U-2 first flew in 1955, which means it cannot account for the wave that drove the project's creation in the late 1940s and early 1950s, and the A-12 first flew in 1962. What is not in dispute is that a meaningful fraction of the 701 cases the Air Force had publicly classified as Unidentified were unidentified for one reason: the explanation was classified above the clearance level of the people the public had been told were doing the investigating. The CIA admitted this in 1997. Project Blue Book was never told.

Blue Book: The Trick

On August 9, 1966, three months before the Condon Committee began its formal work, the committee's own coordinator sat down at a typewriter and produced a one-page memorandum. He addressed it to two senior administrators of the University of Colorado. He called it Some Thoughts on the UFO Project. He used the word trick to describe the structure he was proposing. The trick, he wrote, would be to describe the project so that, to the public, it would appear a totally objective study, while the scientific community would see a group of nonbelievers with almost zero expectation of finding a saucer. The next sentence was the operating instruction: stress investigation, not of the physical phenomena, but rather of the people who do the observing. Three months before the work began, in writing, the coordinator of the United States Air Force's independent scientific review of unidentified flying objects had laid out how the verdict would be reached.

This is the third and final episode of the Project Blue Book triptych. It picks up where Episode 8 ended, in April 1966, with Gerald Ford's hearings ordered and an independent civilian review on its way to the University of Colorado. It runs through the Portage County chase of April 17, 1966, where four Ohio and Pennsylvania officers chased an unidentified object 85 miles across two states and were told by Project Blue Book they had chased the planet Venus. Six months later, in a Cleveland Plain Dealer interview carried on the Associated Press wire, Officer Dale Spaur told the country what the Venus explanation had cost him. The Air Force itself, on its own letterhead, in a May 17, 1966 letter from one of its information officers, conceded that one of the four officers had been driven off his police force by the consequences of the explanation.

The episode walks through the Condon Committee's collapse from the inside. The Low memo, read in full. James E. McDonald walking into a House Committee on Science and Astronautics hearing on July 29, 1968, alone, the only senior atmospheric physicist of his rank in the country saying on the record that Project Blue Book was scientifically incompetent. The leak of the Low memo to Look magazine in May 1968. Mary Louise Armstrong's resignation. Saunders and Levine fired. J. Allen Hynek's October 7, 1968 letter to Colonel Raymond Sleeper, eight numbered observations, twenty years of complicity finally written down. The Condon Report. The National Academy of Sciences endorsement. The 1997 CIA admission, by Gerald Haines, that high-altitude reconnaissance flights accounted for over half of the late 1950s and 1960s UFO reports. The December 17, 1969 termination announcement, dated to avoid extending the project into a fourth decade.

And the Bolender Memo. October 20, 1969. The single sentence on Air Force letterhead that establishes that UFO reports of national security interest were not, and as of that date had not been, processed through Project Blue Book. They went through JANAP 146 and Air Force Manual 55-11, the operational reporting channels. The episode is honest about what the memo does and does not say. It does not establish a parallel UFO program. It establishes that Project Blue Book, the public investigation that the Air Force pointed to in press statements for twenty-two years, was not the destination of the reports the Air Force itself considered nationally significant. Sixteen pages of attachments referenced in the memorandum are missing from the Air Force's files. They have never surfaced.

Previous episode: Blue Book: The Decline. Next up: What Got Classified, the episode that follows the Bolender Memo's pointer through JANAP 146 and AFM 55-11 into the channels Project Blue Book was never the destination of.
