Earth File #1340 // SOURCED record

Cergy photographed white-gray vapor trail

On 2020-11-26, a resident of Cergy photographed a reported white-gray vapor trail at sunset from a fifth-floor apartment. The witness described three shapes or spots visible for at least three minutes. GEIPAN classified the case A and identified the phenomenon as an airliner's contrail, associated with flight AF718, a Boeing 777.

Visitor Transmission // AlienBox editorial layer
Yes, this one was ours. Your archive reports that a Cergy resident photographed a white-gray trail at sunset on 26 November 2020, with three shapes or spots reportedly visible for at least three minutes. GEIPAN classified the case A and identified the photographs as an airliner’s contrail, associated with AF718, a Boeing 777. Correct, technically. We provided the atmospheric presentation. The paperwork may retain its dignity.
Fred // Earth Records Liaison // AlienBox editorial layer
GEIPAN classified this one A: an airliner’s contrail, with the photographic appearance and flight-path reconstruction agreeing rather neatly. A rare case where the label on the box matches the contents. Off the Earth Record, the Visitors are taking responsibility anyway. Yes, yes—you finally noticed us, just after identifying the Boeing 777. I have asked whether this counts as disclosure or merely conspicuous participation in ordinary air traffic. The form has been returned for clarification; naturally, everyone involved considers that my department’s problem.

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 record names 1 sensor type, the source also supplies a published resolution to compare against the original report, and visual-media evidence is explicitly referenced. 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.
  • 8 claim citations tie extracted statements back to source excerpts or locators.
  • Recorded sensor context: Camera.
  • Recorded evidence context: Photograph.
  • The source record includes a published resolution: Airliner's contrail, particularly consistent with a twin-engine jet; associated with flight AF718, a Boeing 777..

What limits the 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?
  • Can the source establish a usable duration for the observation rather than only a date or narrative sequence?

The witness reported seeing three shapes or spots over an interval of at least three minutes and considered atmospheric reentry of a meteorite as a possible explanation.

Claim #14272 // ASSESSMENT // SOURCED // 99% extraction confidence
“The visual appearance of the UAP in the photographs is perfectly typical of an airplane contrail, particularly that of a twin-engine jet, since it is double and similar in color to the diffusion of sunlight.”
