30-second briefing
Start with what the primary record actually says.
A ground trace and physical samples gave investigators something to examine beyond witness memory.
Reading rule
An official record establishes what was documented. It does not automatically validate every interpretation or claim contained around it.

Evidence ledger
Trace every finding back to the record.
F-02Data limitation
Where the evidence stops
Documented physical changes do not by themselves identify the cause, vehicle, intelligence, or origin.

Conclusion boundary
Know exactly where the evidence stops.
What the primary record establishes

Method and limits
How this case was assembled.
This chapter follows official records outside one national system. It compares what each archive preserved, what its investigators could test, and what remains inaccessible or incomplete.
- 01
Use the responsible national archive or scientific agency as the primary source.
- 02
Keep local terminology and classification rules attached to the institution that used them.
- 03
Compare systems without pretending that their categories measure exactly the same thing.
Methodological caution
Official records preserve provenance, observations, assessments, and testimony at different evidence levels. Later data may revise how the same record is understood.
05
Historical thread
Follow the record as it changes.
- 1981
Investigators reach the scene
The 1981 report led to site examination and sample analysis, making it a landmark in French case history.

Vastward interpretation
Stay curious without outrunning the evidence.
Independent editorial layer
The notes below are Vastward’s interpretation. They are not statements written by the source agency or witnesses.
Physical evidence raises the evidential ceiling, but only if collection timing, controls, contamination, and alternative causes are tracked.
A trace is a new dataset, not an automatic answer.
- Archive provenance
- The traceable path showing which institution created, held, transferred, and published a record.
- Classification system
- The local rules an organization uses to describe whether a report is identified, insufficiently documented, or unresolved.
