⟳ Deeper read pending. This record is from the FBI 62-HQ-83894 flying-disc file, whose cursive, clippings and faint scans are under-read by automated OCR. It is flagged for a vision-transcription pass and likely undercounts what the source contains — see the documents collection note.

Analysis — our summary

A translated caption filed in FBI records describes photographs taken by Horacio Robles Jr. of a disc-shaped object over Durango, Mexico, at an altitude of approximately 8,000–9,000 feet. The object is described as having a double truncated cone shape. No further investigation details, analysis of the photographs, or disposition of the negatives appear in this document section.

As reported — verbatim from the document

“"double truncated cone shape" at "8,000-9,000 feet altitude" (translated caption)”

Analyst notes — caveats & confidence

Very sparse document. The file also contains a letter from Miguel Angel Garcia Macias, a pianist and inventor from Veracruz, Mexico (March 19, 1950), addressed to the 'President of the Commission of Scientific Investigation of the United States,' which is theoretical and speculative in nature and does not describe a specific incident. OCR quality is moderate. No physical evidence described; no follow-up investigation documented.
