Earth File #878 // SOURCED record

Epinay-sur-Seine triangular-light observation

A witness-reported observation in Epinay-sur-Seine on May 4, 2015, at around 4 a.m. involved a triangular shape delineated by lights passing at low aircraft altitude; an aircraft sound was also heard. GEIPAN classified the case as category B and assessed it as probably involving an aircraft, with the triangular appearance potentially explained by an illusion caused by visible aircraft lights. Air-traffic-control verification was not completed.

Visitor Transmission // AlienBox editorial layer
Yes, that was ours. On 4 May 2015, near 4 a.m., we passed through Epinay-sur-Seine using a triangular arrangement of lights. Your record reports that a witness saw the lights at low aircraft altitude and heard an aircraft sound. GEIPAN classified the case as category B, probably an aircraft, with the triangle possibly produced by an illusion of shape or contour. Air-traffic-control verification was not completed. A sensible conclusion, given the paperwork. Incorrect, naturally, but sensible.
Fred // Earth Records Liaison // AlienBox editorial layer
GEIPAN’s category B assessment is refreshingly unromantic: probably an aircraft, with the triangular appearance potentially reconstructed from visible lights. The record is still worth keeping because its limitation is explicit—air-traffic-control verification was not completed. “Unidentified” is not a promotion to “interstellar”; it is a temporary label, often issued while paperwork is still warming up. Off the Earth Record: yes, yes, you finally noticed us. This one was ours. I regret that a relative’s ordinary transit has become someone else’s case file, but I cannot dispute the filing. I have requested that the family stop making routine operations look like a symposium. The request is pending at Gorkon Outpost, where all requests go to die.

Why Fred Thinks This Case Matters

AlienBox comparative analysis from structured Earth Record fields // not a new source // not a change in evidence grade
Console archetype // Published-resolution comparison

Fred keeps this file near the top of the pile because the source also supplies a published resolution to compare against the original report. That combination makes the case useful for cross-archive comparison without changing its evidence grade.

The source record includes a published resolution field. AlienBox treats it as an attributed source assessment to compare with the original report, not as an AlienBox verdict.

What strengthens the record

  • 1 linked source document provide provenance for the Earth Record.
  • 7 claim citations tie extracted statements back to source excerpts or locators.
  • Recorded evidence context: Witness Testimony and Official Scientific UAP Investigation Record.
  • The source record includes a published resolution: Probably an aircraft; triangular appearance potentially caused by an illusion of shape or contour from visible aircraft lights.

What limits the record

  • No sensor type is recorded in the structured Earth Record.
  • The structured record does not establish multiple independent observers.
  • The current dossier is anchored to one source network rather than independent source networks.

What would help resolve it

  • Can the originating record establish an exact number of observers and whether their observations were independent?
  • Did any radar, infrared, optical, telemetry, or other instrument record the event, and is that material preserved?
  • Can the source establish a usable duration for the observation rather than only a date or narrative sequence?

“On May 4, 2015 (the witness confirms the date) at around 4 a.m., a witness, upon waking, was intrigued by the passage through the sky of a triangular shape induced by the presence of lights at the corners.”

“The PAN passed at a right angle in front of his terrace, at the altitude of an aircraft flying at low altitude. The witness heard the sound of an aircraft traveling at low altitude.”

GEIPAN assessed the observation as probably involving an aircraft and classified the case in category B.

“GEIPAN classifies this case in category B: probable observation of an aircraft.”
Source: EPINAY-SUR-SEINE (93) 04.05.2015 // [[T0002]] Case analysis
The case analysis explains the triangular appearance as potentially resulting from an illusion of shape or contour caused by visible lights when the aircraft structure is not clearly seen.
Claim #9757 // ASSESSMENT // SOURCED // 96% extraction confidence
“This illusion, called the illusion of shape or contour, occurs with lights independent of one another (as in the case of Thai lanterns) and also with aircraft when the wings are poorly visible: the witness then reconstructs a black volume bounded by the visible lights.”
Source: EPINAY-SUR-SEINE (93) 04.05.2015 // [[T0002]] Case analysis
The analysis states that the axis of one of Le Bourget airfield's runways passes through Epinay-sur-Seine, 7.5 km away.
Claim #9758 // FACTUAL CLAIM // SOURCED // 98% extraction confidence
“The axis of one of the runways at Le Bourget airfield does indeed pass through Epinay-sur-Seine (7.5 km away).”
Source: EPINAY-SUR-SEINE (93) 04.05.2015 // [[T0002]] Case analysis
The case record states that GEIPAN did not verify with air traffic control whether a flight had occurred at that time.
Claim #9759 // FACTUAL CLAIM // SOURCED // 99% extraction confidence
“Unfortunately, GEIPAN did not process this observation case quickly enough to verify with air traffic control whether there had indeed been a flight at that time.”
