26 November 2019, shortly after 17:00 local; principal close appearance about 20 seconds
Outcome: Open (Unresolved). GEIPAN retained D1 after comparing actual Robin DR400 and Mirage 2000 activity with the accounts. Neither match was adopted; testimony from the couple was not fully independent and no event recording was available.
Two cars on the journey home
A couple driving separate vehicles from Vesoul towards Villers-lès-Luxeuil reported an unusual appearance on 26November 2019. The husband first noticed a distant white light near Saulx; his wife did not see that phase. Later, near Villers, both described a dark triangular appearance carrying white and red lights.
Those phases should not be treated as two independently confirmed objects. Only one observer described the earlier light, and its identity with the later appearance was not instrumentally established. Keeping the journey together avoids artificially multiplying the case.
From initial enquiries to a later report
An association began the enquiry before GEIPAN took it over, with an investigator involved in both stages. Questionnaires were submitted inDecember 2019; further contacts in 2022 revisited the chronology. The published technical report is datedJanuary 2025.
The witnesses described silence and a low, slow passage. These are reported impressions, not a measured flight profile. Their experience of local military aircraft is relevant context, but familiarity alone cannot establish an unknown object’s distance, altitude or size.
Ordinary aircraft were genuinely present
The enquiry identified a Robin DR400 whose landing flight and lighting offered a possible match. Mirage 2000-5F exercise activity also supplied a concrete candidate. These were not abstract suggestions that any aircraft might have been in the area.
GEIPAN nevertheless found mismatches: the apparent dark form and size were difficult to reconcile with the Robin, while the Mirage comparison involved timing, elevation, size and perceived-noise problems. A military-drone transit notice was examined too, but its designated high-altitude conditions did not fit the reconstructed view below cloud.
Keeping the actual flight candidates visible
The Robin’s lights and route supplied points in favour of an ordinary aircraft. The Mirage offered a better broad shape comparison but, in the reconstructed chronology, involved roughly ten minutes’ timing difference and a substantially lower viewing elevation. GEIPAN did not adopt either identification.
The outcome therefore does not mean no aircraft could explain the view. It means the published investigation did not establish a satisfactory correspondence. A better synchronized chronology or more precise flight reconstruction could change the balance. Suppressing the real aircraft because the case remains Open would make the article less informative.
What remains unsettled
The report retained D1 after considering those possibilities. It also states that the spouses’ accounts cannot be treated as fully independent and that no photograph or video corroborates the appearance. The current classification is therefore Open (Unresolved), rather than a claim that aircraft were absent.
This is a useful distinction between an investigated candidate explanation and a demonstrated identification. A real nearby flight can strengthen an explanation without proving it; a mismatch based on remembered size can weaken that explanation without proving exotic technology. The decisive evidence would link a specific source to the observed direction and time with fewer dependencies on recollection.
