TRANS-EN-PROVENCE

Opening

On the afternoon of 8 January 1981 Renato Nicolai, a farmer at Trans-en-Provence in the Var, heard a whistle and saw a lead-coloured disc come down on his property. It sat briefly on the ground, lifted, and left. He found a circle on the packed earth, traces on plants, and called the gendarmerie. GEPAN, the French official study group, sent investigators. They sampled soil and vegetation. The lab paper said the ground had been compressed and heated in a way they did not shrug off as a tyre.

France treated this as a physical-trace case, not as a club night. Nicolai was not a lecturer. The circle was measured. The record became the showpiece of GEPAN's early work because something had been done to the dirt.

Timeline

8 January 1981, about 17:00Nicolai on his own ground near the house. A whistle. A dark disc, two metres or so across in his first telling, stand-like parts underneath, down onto packed earth and up again in seconds. He waits. He walks over. A circle. Plants looking wrong. He calls the gendarmes rather than a newspaper.

Gendarmerie the same day or the next. Photographs. Measurements. A ring a couple of metres across, soil compacted, vegetation affected in and around the mark. They treat it as a scene, not a joke.

GEPAN follows. Samples leave for labs. Through 1981-83 the technical notes describe mechanical pressure and heat, pigment changes in plants, a pattern they will not file as a tractor prank. Critics later argue contamination and over-read chemistry. That fight is later. The ring is 8 January.

The case becomes the physical-trace card French official study shows first. Nicolai stays a farmer. The disc does not come back for a second sitting.

Key figures

Renato Nicolai is the witness. A man on his own land, not a television booking.

The gendarmes own the first official look at the circle and the first photographs.

GEPAN investigators and the contracted labs own the soil paper that made the case famous.

Later sceptics own the chemistry argument. They do not own the afternoon mark.

Physical and documentary trail

The trail:

One: Nicolai's account of a whistle, a descent, a short sit, a lift.

Two: the circular ground trace photographed and measured by gendarmes.

Three: plant damage in and around the ring.

Four: GEPAN laboratory notes on compaction and heat.

There is no photograph of the disc on the soil. There is no fragment with a serial. There is no second farmer who filmed the descent.

Things you might not know

• Nicolai was 55. He was a 55-year-old farmer when the disc came down on his land.
• The marks were not a clean circle. The traces were two rough semicircles crossing each other. The object he described was about 2.5 metres across and 1.5 metres high.
• The alfalfa lost its chlorophyll. Leaves of alfalfa near the landing site showed chlorophyll levels 30 to 50 percent lower than expected.
• The gendarmes first said tyres. The police report suggested the marks looked like a car's tyre tracks. GEPAN set that aside because the only witness disagreed.
• There is an army base nearby. The farm is close to the Canjuers military camp, one reason a secret military device is often suggested.

Competing explanations

A landed device that left heat and weight in the dirt. This is GEPAN's working tone. It has samples. It has no machine.

A vehicle or a prank that the labs over-read. Possible. Has to live with official chemists who would not call it a tyre.

A meteoritic or mundane heat scar mis-seen. Poor fit for a farmer who watched a descent.

Later life of the case

Trans-en-Provence became the case France's official UFO study put first, and the one sceptics argue about most. GEPAN was renamed SEPRA and later GEIPAN, which still investigates sightings for the French space agency and publishes its case files. Nicolaï never reported a second landing. For the earlier French case of a farmer and a craft in his field, see Valensole.

Finding

Renato Nicolai saw a disc sit on his land at Trans-en-Provence on 8 January 1981, the gendarmes measured a ring, and GEPAN's labs wrote that the soil had been compressed and heated.

What still will not resolve: a photograph of the disc on that ring, or a fragment with an 8 January chain.
