A man near Trans-en-Provence in southern France told gendarmes a craft had landed briefly on his property and left marks on the ground. Gendarmes took samples, and GEPAN analyzed the soil and plants in a 1983 technical note. It remains one of France's most discussed cases.
Dec 1981 Sightings
Residents of Norway's Hessdalen valley began reporting strange lights in December 1981, up to about 20 a week into 1984. Project Hessdalen ran an instrumented field study in 1984, and Ostfold University College set up an automatic measuring station in 1998. Their cause is still debated.

A TV crew aboard a Safe Air Argosy cargo flight filmed lights off the Kaikoura coast, with returns reported on Wellington radar and the plane's own radar. An Air Force inquiry concluded natural but unusual phenomena; UN-post files released in 2021 show DSIR scientists left them unidentified.
