Kinross UFO Incident — Project Blue Book and the Record

Kinross UFO Incident — Project Blue Book and the Record

Project Blue Book's Investigation

Project Blue Book*** — the U.S. Air Force's official UFO investigation program, headquartered at Wright-Patterson AFB in Ohio — did investigate the Kinross incident. Its final classification attributed the case to pilot error*** (specifically vertigo) and concluded that the mission had resulted in the aircraft crashing into Lake Superior.

The Blue Book file, unlike many other entries in the program's database, does not appear in the publicly available Blue Book records in the manner that researchers and NICAP expected.

The NICAP Expungement Claim

The National Investigations Committee on Aerial Phenomena (NICAP)***, directed by Donald Keyhoe, made a specific and serious claim about the Kinross case's Blue Book record:

"NICAP claimed that any mention of the mission had been expunged from all official records held by Project Blue Book."***

This claim — that the Blue Book file was altered or sanitized to remove specific mission details — represents an allegation of deliberate evidence management, not simply inadequate investigation. NICAP stated that when they requested official documents under applicable procedures, they were told by the Air Force that no records existed*** pertaining to the incident.

The absence of expected records is itself a form of evidence. An air defense intercept mission that resulted in the death of two personnel and the loss of a military aircraft would normally generate extensive documentation: mission reports, radar operator statements, search and rescue records, accident investigation reports, next-of-kin notification records. The claimed absence of these records from the official archive is not explained by simple bureaucratic inefficiency.

Donald Keyhoe's Leaked Document

Donald Keyhoe claimed to have obtained a leaked Air Force document from 1958 — five years after the incident — which described the Kinross incident in terms that went significantly beyond the official public explanations. According to Keyhoe, the document:

• Characterized the incident as "a UFO encounter of the strangest kind"***
• Quoted a radar observer from the night of the incident: "It seems incredible, but the blip apparently just swallowed our F-89."***

The phrase "just swallowed our F-89" — attributed to an Air Force radar operator in a classified internal document — is one of the most compelling pieces of evidence in the case because:

• It comes from a ground controller who was watching the radar in real time
• It implies the controller's own interpretation of the event was that the F-89 was somehow consumed or absorbed by the unidentified object
• It was allegedly written in an internal document where there would be less pressure to conform to the official public narrative

Keyhoe was not generally given to fabrication, and his access to Air Force sources was extensive. Whether this specific document exists and whether the quoted language is accurate cannot be verified from publicly available sources.

The Broader Blue Book Context

The Kinross incident occurred during the period when Project Blue Book was under significant institutional pressure to produce conventional explanations for UFO reports — the Robertson Panel had just recommended an active public debunking program in January 1953. A case in which an Air Force aircraft disappeared while intercepting an unidentified object — with no conventional explanation surviving scrutiny — would have been exactly the kind of case that created institutional pressure to classify or sanitize.
