The Ussy-sur-Marne gendarmes' triangle

In the early hours of 24 June 1994 a gendarmerie patrol in Seine-et-Marne watched a triangular object come to a halt above their car, then leave at dizzying speed while their radios went dead. Their official report went to France's UAP unit, which could not explain it. This is the record of what was reported, not a verdict on what was in the sky.

◆ THE SHORT VERSION

  • The Ussy-sur-Marne gendarmes' triangle is a reported UAP case in Ussy-sur-Marne, Seine-et-Marne, France, 24 June 1994.
  • Three gendarmes on night patrol reported a triangular object that came slowly towards their car and stopped above it.
  • When they drove on, their report says, it left westward at dizzying speed and within a second was only a faint point.
  • Their procès-verbal records that two radio sets in the car went dead, though they could not say when.
  • GEIPAN holds the gendarmes' own report and classes the case D: no explanation could be found.
  • For this case Fractured Realities holds 1 distinct source, 1 corroborating primary document and 1 claimant on its resolved list.
  • The archive grades it L4 · OFFICIAL RECORD — a released government record names who saw it, the top of our scale, though no independent testimony sits beside that record.

Counts are resolved totals of what sources say, computed 2026-10-03; the reported details above are claims in the record, not findings. A record of reports, not a verdict on what happened.

At 02.47 on 24 June 1994 three gendarmes on night duty were driving out of Ussy-sur-Marne towards Changis-sur-Marne. Level with the village football ground the driver pointed out a very bright light above the A4 motorway bridge. As they closed in, it resolved into three yellow-white points forming a triangle. Then they saw that the lights belonged to an object. Its underside was triangular with a pyramid-shaped centre pointing at the ground. They stopped, and it came slowly towards them at the same height and halted above their vehicle. When they drove on, it left westward "à une vitesse vertigineuse" (at dizzying speed). Within a second only a faint point remained.

What is on the record

The source is GEIPAN, the unit of the French space agency CNES that investigates reports of unidentified aerospace phenomena. Its file 1994-06-01360 carries the gendarmes' own procès-verbal, report no. 1544/94. The report notes that two radio sets went dead: "le BPH et le saphir se sont éteints" (the BPH and the Saphir sets went off). The gendarmes could not say at what moment. They put the sighting at about ten minutes. The night was hot and the windows were down. There was no noise, no smoke and no smell. A Météo France weather record, a drawing and a site plan were attached. The report was closed on 1 September 1994. The names and the unit's name are blacked out. Its unit code, 05264, is not.

GEIPAN classes the case D, its category for a phenomenon investigated and not identified: "aucune explication n'a pu être apportée" (no explanation could be found). The file lists no hypotheses tested. Press coverage since, including France 3 in 2021, repeats GEIPAN's summary. A local account names the brigade, but the released report does not.

Why it sits where it does

This case grades L4, an official record. A released government record names who saw it: three serving gendarmes, identified by their unit in their own report. No independent testimony sits beside that record. The tier measures sourcing, never truth. What the record firmly holds is a patrol's official account of an object above their car and two radios that stopped. What was over the A4 is not resolved here.
