UAP Evidence & Medical Classification – A History of Government Protocol

An investigation into the military protocols used to classify unidentified aerial phenomena, the parallel files used to hide them, and the Special Access Programmes currently restricting witnesses' medical records.

The United States Department of Veterans Affairs paid John Burroughs full disability compensation in 2015 for cardiovascular injury sustained on overnight patrol in a Suffolk forest. The original military medical evaluations that documented the injury remain inside a Special Access Programme, and Burroughs’ civilian cardiologists have never been allowed to read them.

This document tracks the evolution of a single government protocol that identifies abnormal phenomena and then manages the witness through classification and medicalisation.

Data Manifest

  • Primary Investigation: The evolution of military protocols to classify unidentified anomalous phenomena and the subsequent restriction of witness medical evaluations.
  • Key Anomalies Documented: Discrepancies between internal analysis and public briefing figures (1955); concealment of origin logs (1975); SAP classification of medical records following acknowledged cardiovascular injuries (1980 to 2015).
  • Primary Sources Utilised: AFR 200-2 (1954), Project Blue Book Special Report No. 14 (1955), NMCC Logs (1975), DIA DIRD-26 Report (2010), VA Settlement Records (2015).

Glossary

  • UAP (Unidentified Anomalous Phenomena): The current official term for unidentified flying objects and related phenomena, used to categorise aerial and space-based sightings that defy conventional explanation.
  • Project Blue Book: The United States Air Force's official investigation into reports of unidentified flying objects, which ran from 1952 to 1969.
  • Air Force Regulation 200-2 (AFR 200-2): The 1954 internal rulebook that told Air Force units how to investigate and report unidentified sightings, explicitly ordering the reduction of unsolved cases to a minimum.
  • Chi-square statistical test: A standard maths test that compares two groups of data to work out the probability that any difference between them happened by chance.
  • Defense Intelligence Reference Document (DIRD): A formal in-house intelligence report written for the Department of Defense, restricted in distribution.
  • Non-ionizing electromagnetic radiation: Energy waves (such as microwaves and radio waves) that do not carry enough power to knock electrons off atoms, but that can still heat or damage human tissue at high enough intensity.
  • Special Access Programme: A United States security classification above ordinary Top Secret that limits access to a tightly controlled list of named individuals.

The Roots of UAP Policy

In January 1953 the Central Intelligence Agency convened a scientific committee under the physicist H.P. Robertson. Its brief was a review of the Air Force investigation into unidentified flying objects, then running as Project Blue Book. Robertson’s panel concluded that the objects posed no direct national-security threat, but that public interest in them did.

The panel recommended a public-education programme of debunking and ridicule, alongside close monitoring of civilian investigation groups. From that point, the operational target shifted from the objects to the witnesses.

Air Force Regulation 200-2

Eighteen months later the Air Force codified the doctrine in writing. Air Force Regulation 200-2 (AFR 200-2), dated 12 August 1954, set the reporting, investigation and analysis procedure for unexplained aerial reports. Buried in the text was a direct instruction to ‘reduce the percentage of unknowns to the minimum’.

The same regulation restricted what base commanders could say in public. Information could be released to the press only if the sighting had been positively identified as a known object. Anything still classed as unidentified stayed inside the building.

According to Captain Edward J. Ruppelt, the former head of Project Blue Book, the duty officers maintained a second file alongside the standard case route. Ruppelt called it the ‘C.P.’ file, short for crackpot, and reported in his 1956 book that any case involving entities, occupants or direct contact was dropped into it and closed without standard scientific review.

What Ruppelt described has not been published by the Air Force in any internal manual or operating procedure. The C.P. file survives in the public record as a verbal description of a sorting practice rather than a documented institutional rule.

The Battelle Report

Inside the building the figures were precise. Battelle Memorial Institute, contracted by the Air Force, ran four analysts over 3,201 sighting reports collected between 1951 and 1954. Their classification work returned 21.5 per cent of cases as completely unknown.

That was not the only finding.

Battelle’s analysts then ran a chi-square statistical test, a standard mathematical test that compares two groups of data to work out the probability a difference between them happened by chance. Applied across six observable characteristics of each report, it returned a probability of less than one per cent that the knowns and the unknowns had come from the same population.

A second result cut in the opposite direction to the public line. Of cases the analysts graded ‘excellent’ for data quality, 35 per cent stayed unknown after investigation. Among ‘insufficient’ cases, only 3.9 per cent had been rated excellent in the first place.

On 25 October 1955 the Secretary of the Air Force, Donald Quarles, issued a press release summarising the report for the public. Quarles told reporters that the unknown category accounted for only 3 per cent of cases. Even that 3 per cent, he added, could be explained as conventional craft or illusions had more data been available.

The drafting memos that took the figure from 21.5 per cent to 3 per cent are not in the public record. No named office or official has been identified as having signed off the conversion.

Inside the same report Quarles was summarising, the chi-square result had been used to argue the opposite of his public claim. Higher data quality, Battelle had found, produced a higher proportion of unknowns, not a lower one.

What the Battelle Analysts Found and What the Air Force Said

Finding Category Internal Battelle Figure Public Quarles Figure
Total cases classified as 'Unknown' 21.5 per cent 3 per cent
Relationship between data quality and identification Higher data quality produced a higher proportion of unknowns (35 per cent of 'excellent' cases remained unknown). Even the residual 3 per cent could be explained as conventional craft or illusions had more data been available.

The ‘Crackpot’ Files

Eleven members of the Sutton and Taylor families arrived at Hopkinsville police station in Christian County, Kentucky, on the night of 21 August 1955. They described a sustained close encounter at a rural farmhouse with small humanoid figures: oversized heads, glowing yellowish eyes, long arms ending in talons. City police, Christian County state troopers and military police from the United States Army installation at Fort Campbell responded to the call together.

What the officers found on site was specific. Broken window screens, bullet holes from a 20-gauge shotgun and a .22 rifle, but no bodies and no blood. All 11 witnesses were visibly terrified.

The Air Force filed the incident as Project Blue Book Case 10073. Inside that classification record the event was logged as a hoax or a misidentification of great horned owls and meteors. No psychiatric evaluation was carried out on any of the 11 witnesses. Medical examination of the witnesses did not happen. Ballistics analysis of the bullet holes does not appear in the file.

The Fort Campbell military police were not re-interviewed under the case number, and the unredacted investigator notes for Case 10073 have not been released.

Loring AFB UAP Incursions

Strategic Air Command security personnel at Loring Air Force Base in Maine logged an unidentified craft hovering at low altitude near the weapons storage area on the nights of 27 and 28 October 1975. The installation housed B-52 bombers, KC-135 tankers and nuclear weapons. Sightings logged a red navigational light and a white strobe, and tracked rapid straight-line movements and turns without an apparent radius.

Internally, the record was direct. The National Military Command Center described the events as a clear demonstration of intent by ‘a smart and capable aviator‘.

Outside the building, the briefing line went the other way. According to Michael Wallace, who served at Loring and spoke to the TWZ archival reconstruction in 2020, base personnel were told to inform the press that the incursions had been harassment by a Canadian helicopter.

Below the airspace incursion, medical staff were watching. According to John E. Morkavich, hospital corpsmen observed the alert response from the roof of the medical barracks as klaxons sounded and Army National Guard helicopters launched.

That places medical staff among the direct eyewitnesses to the incursions. No integrated medical or psychological evaluation of the personnel operating under sustained alert duress during those two nights has been disclosed.

Whether the base hospital or the corpsmen who watched from the roof recorded any unusual physiological symptoms among the security force has not been answered in the released material.

Rendlesham Forest Incident

Around 3 am on 26 December 1980, two United States Air Force airmen were dispatched from RAF Woodbridge in Suffolk to investigate strange lights descending into Rendlesham Forest. Airman First Class John Burroughs and Staff Sergeant Jim Penniston had been told a small aircraft had gone down.

They did not find an aircraft.

Penniston later told the Guardian he had walked up to a brightly lit object on the forest floor, observed hieroglyph-like markings on its surface and touched it. The surface, he said, was smooth and warm. He has since attributed his contact with it to beta-radiation exposure.

Burroughs went through a different exposure. In his own account he was engulfed in a beam of white and blue light at the scene, briefly immobilised and unable to move.

On the second night, Lieutenant Colonel Charles Halt, deputy base commander, returned to the forest with a recording device. In his contemporaneous memo and later testimony he described seeing beams of light projecting from anomalous craft into the weapons storage area at the nearby RAF Bentwaters site.

Burroughs developed cardiovascular complications in the months and years that followed and eventually underwent surgery. He has linked the onset of his cardiac trouble to that night in the forest. The base medical evaluations covering 1979 to 1982 were not released.

According to a public confirmation from Dr Christopher Green, a former Central Intelligence Agency medical officer, the records sit inside a Special Access Programme, a United States classification level above ordinary Top Secret that restricts file access to a tightly controlled named list. The full statutory basis for that designation has not been published. Burroughs’ civilian cardiologists are working without access to the originating military medical record.

The DIA Report on UAP Injuries

The Defense Intelligence Agency completed a restricted internal report titled ‘Anomalous Acute and Subacute Field Effects on Human Biological Tissues’ on 11 March 2010. Catalogued as DIRD-26 (a Defense Intelligence Reference Document, the formal in-house intelligence report format), it was later released via the Agency’s FOIA reading room as FileId/170026. Its title page lists the author’s name as blacked out under exemption (b)(6).

Attribution to Dr Christopher Green, a former Central Intelligence Agency medical officer, has been made publicly by Green himself and is repeated in the 2026 SCIEPublish medical review of the case material.

And the document was specific. It evaluated 42 cases drawn from peer-reviewed medical literature alongside 300 unpublished cases. It concludes that humans have been injured by exposure to anomalous vehicles, primarily through broadband non-ionising electromagnetic radiation and microwave energies, energy waves that do not strip electrons from atoms but can still damage human tissue at high enough intensity.

The clinical catalogue runs long. Skin burns (erythema in the document’s terminology), persistent numbness and tingling, difficulty swallowing, hair loss, extreme sensitivity to light and subacute persistent sleep disorders all appear in the body of the report.

The cellular biology often attributed to DIRD-26 belongs elsewhere. Disruption of cellular signalling inside neurons, drawn by analogy from high-energy microwave and radio-frequency animal models, is set out in the 2026 SCIEPublish review of the wider case literature, not inside the 2010 DIA document. The DIRD-26 text itself does not contain that cellular biology argument.

Where the original clinical files for the 300 unpublished cases are physically held, and which department maintains chain of custody over them, is not stated anywhere in the released text.

The 2015 UAP Disability Settlement

The United States Department of Veterans Affairs granted John Burroughs full disability compensation in 2015 for cardiovascular injury sustained in the line of duty at Rendlesham Forest in December 1980. Senator John McCain and the lawyer Pat Frascogna intervened in the protracted administrative and legal process that produced the settlement.

On its face, that award is a state acknowledgement that an injury caused by an unrecognised craft in a Suffolk forest is a service-connected disability.

According to Dr Christopher Green’s public statement, the original 1979 to 1982 base medical evaluations covering Burroughs’ immediate post-incident health remain embedded inside a Special Access Programme.

Inside the same case file, the state has paid out on a route of injury whose primary clinical evidence it has not released. Burroughs has confirmed publicly that the 1979 to 1982 evaluations remain sealed, and his civilian cardiology team is treating him without access to the originating military medical record.

Precise statutory authority for keeping the files sealed has not been disclosed, and the Special Access Programme designation cited by Green has not been published.
