GEIPAN Case 2014-06-50078 — ETRELLES (35) 01.06.2014

Brief

On the night of June 1, 2014, at 23:07, two gendarmerie officers on a proximity-surveillance patrol in the Zone industrielle du Piquet, Etrelles (Ille-et-Vilaine), observed a dark aerial mass bearing two small, faint, greenish-white downward-directed lights. After hovering stationary for less than two seconds above their patrol vehicle, the object accelerated eastward toward Laval at a speed both witnesses described as extraordinary, following a linear trajectory with a slight downward curve before disappearing without sound, trail, or fragmentation. GEIPAN opened a formal inquiry; field investigation eliminated all natural and human-activity explanations, and the case received a D1 classification, GEIPAN's highest-confidence unexplained designation.

Key points

• Both witnesses were Gendarmerie officers on official government patrol duty at the time of observation, lending institutional credibility to the report.p.1
• The dark mass was stationary directly above the patrol vehicle for less than two seconds before accelerating; the driver stopped the car immediately upon sighting it.p.2
• Acceleration was instantaneous with no detectable sound, no vibration, no light trail, and no fragmentation of the luminous points.p.2
• The driver's exclamation — 'nom de dieu ! qu'est-ce que c'est que ça ?' — was cut off before he could finish the sentence, so rapid was the object's departure.p.2
• Estimated altitude was approximately 1,000 meters; apparent size was compared to the volume of two minivan-type vehicles.p.12
• Trajectory ran from approximately 60° above the horizon at first sighting to 20° at disappearance, west to east (RENNES toward LAVAL), on a rectilinear, slightly descending path.p.13
• Situation maps included in the case file explicitly mark the UAP's direction of travel with a directional arrow.p.7
• On-scene inspection immediately after the sighting found no traces, marks, or environmental effects on the ground or surrounding vegetation.p.9
• Both witnesses independently corroborated each other's account before filing the report; their separate procès-verbaux are consistent on all material details.p.2
• The witness who completed the GEIPAN questionnaire self-identified as 'cartesian' in temperament, stated he had no prior strong interest in UAP phenomena, and described being shaken primarily by the velocity of the object.p.16

Verbatim

• cet « OBJET » se déplaçait à une vitesse incroyable en provenance de l'ouest et en direction de l'est

  p.1

• après moins de deux secondes d'immobilité au dessus de notre véhicule, la dite masse s'est subitement déplacée vers la direction de LAVAL, donc vers l'Est. Cet objet s'est éloigné à une vitesse vertigineuse, à une allure absolument stupéfiante.

  p.2

• Le déplacement de l'objet n'a généré aucun bruit, grondement ou tremblement perceptible.

  p.2

• j'ai immédiatement tourné la tête vers mon collègue et j'ai alors compris qu'il avait également été témoin de la même chose.

  p.2

• Le PAN a ensuite disparu de vue, comme-ci il s'était évanoui dans la nature en un millième de seconde.

  p.9

• toute possibilité de confusion avec un phénomène d'origine naturelle ou lié à l'activité humaine semble devoir être écarté.

  p.9

• Je suis formel sur mon observation, toutefois je ne suis pas en mesure de l'interpréter, j'ignore de quoi il s'agit.

  p.16

Most interesting

• GEIPAN's D1 classification is the agency's highest-confidence unexplained designation, reserved for cases where investigation actively eliminates all prosaic hypotheses rather than merely finding data insufficient.
• The patrol vehicle was moving at low speed through the industrial zone when the object was spotted through the windshield — the driver stopped immediately, providing a stable observation platform for both witnesses.
• One witness exited the vehicle after the sighting to inspect the immediate surroundings for physical traces; none were found.
• The witnesses reported to the Gendarmerie Operations and Intelligence Center (Centre d'Opérations et de Renseignements) by phone at 23:12 — five minutes after the 23:07 sighting — creating a contemporaneous official record.
• The GEIPAN questionnaire explicitly asks witnesses about current medications and alcohol or drug consumption; the witness denied all three, and the gendarmerie officers' professional status makes this self-report more than ordinarily credible.
• The file notes the lights did not form a beam or ray and showed no oscillatory movement while the mass was stationary — characteristics more consistent with fixed onboard illumination than any known aircraft lighting convention.
• The apparent size estimate — 'peut-être équivalent à un volume de deux véhicules de type monospace' — was offered while acknowledging the night conditions made precise determination impossible.
• The GEIPAN questionnaire used is version 3.5 dated June 2013, indicating a standardized investigative protocol was in active use at the time of the June 2014 sighting.
