28 August 2014, around 05:00 local; duration estimated at ten minutes
Outcome: Open (Unresolved). GEIPAN retained D1 after interviews and checks of weather, satellites, re-entry and projected lights. The reported second observer was never identified, and no recording establishes the formation’s distance, size or identity.
An early-morning account from coastal Corsica
The official case is named Zonza, but the observation was near Sainte-Lucie-de-Porto-Vecchio, in the coastal part of that commune. A camper described a large dark circular appearance with central lights, accompanied by rows of smaller dark forms moving steadily across the sky. He estimated the duration at ten minutes.
That description does not justify a fleet count or a precise craft design. The witness could not establish the distance or dimensions, and was unsure of some smaller shapes and groupings. Those uncertainties belong with the account, rather than disappearing from a dramatic reconstruction.
What the investigation actually obtained
The witness made a gendarmerie statement; GEIPAN assigned an investigator in September and received a questionnaire in October. The December 2014 report records an interview and environmental checks. Although the witness mentioned briefly encountering another camper who appeared to be watching, investigators obtained no statement from that person.
This is therefore one documented witness account. An unnamed possible observer is a lead, not independent corroboration. The distinction matters particularly when a proposed visual or perceptual explanation is judged partly against the suggestion that someone else saw the same thing.
Checking ordinary possibilities
The investigators examined atmospheric conditions, satellite passages, a recorded re-entry and a local nightclub’s searchlight. The re-entry did not match the reported time and direction; the lighting equipment was reportedly not operating then. Weather information did not provide a convincing cloud explanation.
The report also records a limitation in its aviation enquiries: investigators were not received by responsible personnel at Solenzara. A statement about no relevant military radar activity is not equivalent to a publicly available complete radar reconstruction. The file should not be described as having eliminated every aircraft that could have been present.
Details that resist a precise reconstruction
The report records uncertainty about the smaller forms and whether some were triangular. It also notes a discrepancy between the witness’s reference to moonlight and the astronomical conditions checked by the investigators. These details are reasons to preserve the account carefully, rather than render a perfectly specified formation as if its geometry had been measured.
The roughly constant movement offered no documented acceleration or evasive behaviour. Describing dark forms in a group does not establish that separate machines communicated or acted together. For this entry, the directly supported feature is the report of multiple lights within a broader dark appearance.
An unresolved report, without measured performance
GEIPAN concluded D1, retaining an unexplained observation after investigation. It specifically did not regard the reported motion as demonstrating intention. The current case record still lists the incident as unidentified.
Open (Unresolved) here preserves that finding while keeping its limits visible. There is no authenticated film, measured range or verified independent witness in the reviewed report. A future identification would need to fit the reported setting and sequence, but uncertainty about those details also limits how decisively any proposed explanation can be excluded.
