The researched reading
A real disappearance with an eerie tape. Disorientation, misread planets or reflected lights, or a deliberate vanishing fit the facts at least as well as an encounter, but with no wreckage the case cannot be closed.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 38% | Venus, Mars and Mercury were bright low in the west that evening, and a pilot in a banked or inverted attitude could take his own lights reflected on the sea for an object above him. |
| Perception, memory or mind | 22% | A 20-year-old with limited night experience over Bass Strait is a textbook case for spatial disorientation and a graveyard spiral, in which a pilot loses track of up and down and misreads lights. |
| A hoax or fabrication | 15% | Investigators considered a staged disappearance or suicide; Valentich was a UFO enthusiast and some details of his flight plan were odd. |
| Genuinely anomalous | 15% | The official tape records a calm pilot describing an object with a green light orbiting him, and the plane was never found; some locals reported odd lights that night. |
| A known natural phenomenon | 5% | Night over open water with no horizon is itself the hazard; no special weather is needed. |
| A poorly understood natural phenomenon | 3% | Nothing measured points to an unknown atmospheric light. |
| Secret human technology | 2% | No military aircraft was reported in the area. |
Official position: The Australian Department of Transport could not determine the reason for the disappearance and presumed the pilot dead.
