does not mean
extraterrestrial.

The UAP problem is not a shortage of cases. It is a shortage of data. This database separates what a document recorded from what was added later — case by case, claim by claim.

Established

  • — UAP are a real category of reported observation, continuous since 1946.
  • — A dozen-plus states ran or still run their own investigative programmes.
  • — The Pentagon confirmed the authenticity of three US Navy recordings.
  • — Some cases remain unresolved despite rigorous investigation.
  • — The phenomenon is global, not American.

Not established

  • — That any case involves an extraterrestrial craft.
  • — That any non-terrestrial craft or material was ever recovered.
  • — That a confirmed reverse-engineering programme exists.
  • — That any artefact has been scientifically shown to be non-terrestrial.
  • — That the extreme performance in the accounts was ever measured.

Both columns are true at the same time. The entire difficulty of this field sits between them — and most public argument consists of pretending only one of them exists.

RB-47H over the Gulf of Mexico

The crew of an RB-47H electronic reconnaissance aircraft reported a simultaneous correlation: a signal on the passive ELINT receivers, a visual sighting of a bright light, and a reported g…

USS Nimitz / Tic Tac

During carrier strike group exercises, SPY-1 radar operators aboard USS Princeton tracked unusual contacts over several days. On 14 November two F/A-18Fs were vectored to one of them. Four…

Claim ledger

Myth versus document

Not cases — individual sentences. Each with its origin, its status, and what exactly would settle it.

T5“The Tic Tac entered the ocean.”

Contradicted by the witness himself.

T5“The RB-47 tracked the object on three independent radars at once.”

The RB-47H’s onboard equipment was an ELINT / direction-finding suite — a passive receiver of other emitters, not a radar returning echoes off objects.

T1“F-16 radar recorded accelerations impossible for known technology.”

The recordings are authentic, but an F-16 radar does not display the target’s raw position — it displays the output of a tracking filter that smooths and predicts a trajectory.

T5“GOFAST shows an object racing just above the ocean surface.”

The data needed to work it out is on the video itself: viewing angle and range to target are displayed on the HUD.

T5“Project Blue Book left 701 cases unexplained — meaning 701 unknown craft.”

The number 701 is correct: of 12,618 reports investigated, that many remained in the ‘unidentified’ category.

T5“Radar confirmed an object over Rendlesham Forest.”

The UK Ministry of Defence file is unambiguous on this point: no radar confirmation of an unidentified object in that area and timeframe was found.

Source tiers

Every sentence has a level

T1

Primary document

Operational report, case file, gendarmerie protocol, lab result — produced close to the event.

T2

Official statement

Institutional confirmation: ministry statement, authenticity release, agency determination.

T3

Sworn testimony

Witness account given under legal weight — congressional testimony, sworn statement.

T4

Later account / reconstruction

Interview, memoir or reconstruction produced years after the event. The layer most prone to growth.

T5

Media claim

A claim circulating without documentary backing. Recorded because it shapes how a case is read.

Roswell and Rendlesham are built mostly from T4 and T5. Tehran 1976 and Trans-en-Provence stand on T1. That difference matters more than the shape of the object.
