📅 Overview
On January 8, 1981 at 16:00 (local time), in Trans-en-Provence, southern France, farmer Renato Nicolaï (age 55) observed a disc-shaped craft land and take off from his farm. Botanical alterations were detected at the landing site, leading to formal investigation by France's GEPAN/SEPRA (government UFO investigation division) — the best-documented case of UFO physical evidence.

🛂 GEPAN/SEPRA Formal Investigation
France GEPAN (founded 1977):
- On-site investigation next day 1981-01-09
- Gendarmerie + scientists combined inquiry
Botanical analysis:
- 2m diameter circular trace at the landing site
- Alfalfa plant samples collected
- Analysis findings:
- 30-50% chlorophyll reduction
- Accelerated cellular aging
- Unable to explain by chemical burns or natural aging
- Exact mechanism not determined
Soil analysis:
- Micro-cracking + compression traces
- Unable to explain by natural phenomena
🛂 GEPAN Official Conclusion (1983)
- "Difficult to explain by natural phenomena + human artifact"
- Unresolved classification + botanical analysis data made public
📺 Significance
- Best-documented case of UFO physical evidence (plant alterations)
- French government + scientific investigation combination — highest-quality non-U.S. UFO investigation
- 1981 incident: part of European UFO activity era (with 1980 Rendlesham)
- Together with 1989-90 Belgian UFO Wave: Europe's two foremost government UFO cases
