The account
José Antonio Fioco, manager of the Bela Aliança ranch, said that on 20 February 1969 he went out after his pigs grew restless and saw a 4 m disc on landing legs with three figures in shiny suits; one shone a pink light, another looked into a box, and they left when they noticed him. A separate report from January 1969, logged by the Brazilian group SIOANI, also describes a landing and three helmeted figures near Pirassununga.
The sceptical view
Both reports rest on single witnesses and later retellings; the catalogue lists the explanation as insufficient information.
The researched reading
A detailed one-witness landing report with no follow-up. Without corroboration it cannot rise above an interesting account.
| Explanation | Weight | Why |
|---|---|---|
| Perception, memory or mind | 24% | Night-time agitation of animals and a dim scene can be filled in by expectation; memory adds detail in retelling. |
| Genuinely anomalous | 24% | A detailed close-range description of suited figures and a tripod disc is not easily reduced to a known object. |
| A hoax or fabrication | 15% | A single witness, with no physical traces preserved, during a period of heavy UFO coverage in Brazil; invention cannot be excluded. |
| Something known, misidentified | 14% | A parked vehicle, machinery or workers with lamps on a neighbouring property could underlie the sighting. |
| Undetermined | 11% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| Secret human technology | 4% | Brazil’s Air Force academy is at Pirassununga, but no programme fits a landed disc. |
| A known natural phenomenon | 4% | Natural phenomena do not explain the figures. |
| A poorly understood natural phenomenon | 4% | A luminous phenomenon could explain the pink light only. |
Official position: No official investigation; the catalogue lists the explanation as insufficient information.
