FAB Formulário de Relatório sobre OANI — Official UFO Reporting Form

Brief

This is the FAB's official OANI reporting form used within the SIOANI system, a multi-section structured questionnaire built to capture every observable parameter of a UAP encounter. The form collects observer biographical and psychological credibility data, detailed meteorological and environmental conditions at the time of the event, granular physical characteristics of the object including lights, apertures, appendages, and a movement taxonomy, and occupant or crew descriptions down to clothing zipper count. Additional sections log electromagnetic and physiological effects on persons, animals, and equipment, photography and cinematography details, soil-analysis protocols, and the document closes with a dual-signature block requiring sign-off from both the observer and the commanding investigation officer. The archive copy was digitized from the SIOANI collection by Edison Boaventura Jr of the civilian Grupo Ufologico de Guaruja.

Key points

• A psychological and biographical profile of the observer is embedded in the intake form itself — fields for personality, character, drinking habits, and political views function as a structured credibility filter before investigation resources are committed.p.3
• Location fields capture settlement type (fazenda, vila, cidade), terrain profile (flat, mountainous, hilly), and ground cover (pasture, caatinga, forest, crops, mines), enabling systematic geographic clustering of reports.p.5
• Atmospheric conditions are recorded in detail: daytime or nighttime, moon position relative to the observer/OANI axis, lunar phase, star visibility, cloud cover graded from few to fully overcast, temperature class, humidity, and wind intensity and direction.p.6
• The OANI/observer geometry section asks for ground-measured distance, elevation angle in degrees (zero to ninety), and a specific reference landmark such as a power pole, tower, or forest edge to anchor the sighting geometrically.p.7
• A proximate infrastructure inventory catalogs nearby houses, factories, schools, hospitals, military barracks, electric plants, highways, and railways — serving both as a misidentification control and a population-exposure record.p.8
• Physical object characteristics are captured across structured sub-fields covering opacity, translucency type (reflected, ardent, scintillating), light intensity and continuity, headlights, windows, doors, support legs, and lateral protrusions or stripes.p.11
• A movement taxonomy presents discrete categories for the observer to select: rotation, stationary oscillation, stable hovering, zig-zag, dry-leaf flutter ('folha seca'), tumbling, slow maneuvers, and vertical trajectories.p.12
• Occupant description fields collect number of crew, general appearance in free text, voice tone, probable age, height and weight compared to a human, and clothing specifics including colors, number of garment pieces, pockets, zippers, and whether the outfit appeared as a single unified uniform.p.14
• Electromagnetic effects are surveyed across seven equipment categories — recorders, radio transmitters, radio receivers, radar, radio-navigation devices, television, and local artificial illumination — each requiring a note on stoppage and restart distance relative to OANI proximity.p.17
• Section VII closes the form with a dual-signature block requiring sign-off from the observer and the head of the investigating unit (Chefe da CIO), formalizing chain of custody.p.19

Most interesting

• Brazil developed its own distinct terminology — OANI (Objeto Aereo Nao Identificado) — rather than adopting the American UFO or NATO UAP designations, reflecting an independent national framework for the phenomenon.
• Observer credibility is structurally embedded in the form itself: sections on personality, character, drinking habits, and political views are part of the official intake — a design choice revealing how the FAB weighted witness reliability as an independent variable.
• The movement taxonomy includes 'folha seca' (dry-leaf flutter), a technically specific oscillating-descent pattern that appears independently in French GEPAN/SEPRA documentation and in pilot accounts filed with NICAP, suggesting cross-national convergence on observed flight behavior.
• The occupant description section is detailed enough to log clothing zipper count and whether the outfit was a single unified garment — a level of granularity unusual even by the standards of contemporaneous national investigation forms.
• The electromagnetic effects section surveys seven distinct equipment categories, a more comprehensive sweep than the U.S. Air Force's contemporaneous Project Blue Book intake forms.
• The soil-analysis section (page 16) asks for both the test results and the identity of the organization that performed the analysis, establishing a formal chain of custody for physical trace evidence at landing or approach sites.
• The archival copy was digitized not by a government agency but by the civilian Grupo Ufologico de Guaruja, indicating that civil-society researchers played a direct role in preserving official military records prior to the FAB's formal digital archive program under Ordinance 551/GC3.
• The three-quoted archival attribution line appears as a printed watermark on all 19 pages of the digitized copy; the underlying form text is largely illegible due to OCR degradation of the original scanned document.
