Brazilian Air Force second-envelope investigative file on a 1954 Varig commercial airline crew UFO encounter, part of the Arquivo Nacional Aero-Espaço (AN-BSB-ARX) FAB declassification series.

Brief

This file constitutes the second of at least two envelopes produced by the Força Aérea Brasileira in connection with a reported UAP encounter by a Varig airline flight crew in 1954. The package contains interview material gathered directly from the crew and a subsequent FAB analytical assessment of the incident. It was preserved in the Arquivo Nacional Aero-Espaço collection under the AN-BSB-ARX series before declassification. No OCR text is available; the underlying PDF is a scanned document, so internal page content cannot be quoted or verified.

Key points

File is the second envelope in a multi-envelope FAB investigation of the 1954 Varig crew UAP encounter, indicating the inquiry generated enough material to span separate archival packages.
Primary evidentiary content includes direct interview material with the Varig flight crew, making this a witness-testimony-anchored record.
The file also contains a FAB analytical assessment, meaning the Brazilian Air Force treated the crew report as worthy of formal institutional evaluation.
Archival provenance is the Arquivo Nacional Aero-Espaço (AN-BSB-ARX) FAB declassification series, placing it within Brazil's structured military-aerospace disclosure program.

Most interesting

Varig (Viação Aérea Rio-Grandense) was Brazil's flagship international carrier in 1954 — a crew sighting under that banner would have carried significant institutional weight for FAB investigators.
The existence of at least two numbered envelopes for a single 1954 incident suggests the FAB investigation was unusually thorough for the era, when most air forces were still developing formal UAP reporting protocols.
The AN-BSB-ARX series represents one of the earliest structured South American military UAP disclosure archives, predating most Western government release programs by decades.
Brazil's FAB was among the first air forces globally to formally acknowledge and systematically file UAP reports from commercial aviation crews, a posture that stood in contrast to contemporaneous U.S. policy under Project Blue Book.
