The record

An official file preserves that a report was made and examined. It does not, by itself, establish what was seen.

UNVERIFIED - archive at https://arquivohistorico-forcaaerea.defesa.gov.pt/

No document is attached yet. The retrieval is open work.

What is not settled

The confirmed contemporaneous artefact is a statement given to a civilian magazine's correspondent, not a service document. Until the Arquivo Historico produces a 1957 occurrence report this is a distinguished witness with an unlocated file.
