In the Trans-en-Provence case, an unidentified flying object is claimed to have left physical evidence in the form of burnt residue on a field.
Renato Nicolaï, a 55-year-old farmer,[3] heard a strange whistling sound while performing agricultural work on his property.
Trace amounts of phosphate and zinc were found in the sample material, and analysis of resident alfalfa near the landing site showed chlorophyll levels between 30% and 50% lower than expected.
[3] The close proximity of the site to the Canjuers military base makes such a theory generally plausible.
The physical traces shown on the picture are not perfect circles, in fact there are two more-or-less semicircles crossing over each other.
In an interview for French television, Nicolaï confirmed that there were vehicles passing by on the road at the time of the sighting.
