Trans-en-Provence 1981 Ground Trace: Rapid Descent, Localized Heating, and GEPAN/CNES Analysis
To the point
Renato Collini described in 1981 near Trans-en-Provence a brief rim-centered energy discharge from a two-saucer craft that hovered, touched down, and departed, leaving a circular ground trace and a ring around the rim heated to about 600 C with surrounding vegetation largely undisturbed, and GEPAN/CNES investigators concluded the trace formed during departure rather than on impact, indicating a localized thrust and urging tighter trace investigations.
