On January 19, 1966, around 9:00 am, George Pedley, a 28-year-old rural worker employed at Albert Pennisi's Euramo Banana property near Tully (tropical North Queensland, Australia), was driving his tractor along a path parallel to Horseshoe Lagoon when he reported hearing a loud hissing sound. Looking toward the lagoon, he observed a grey-blue metallic disc-shaped object, about 7.5 metres (roughly 25 feet) in diameter and 2.7 metres (about 9 feet) thick at the centre, rising from the water to treetop level, tilting slightly to one side, and then rapidly moving off toward the south-west until it disappeared. It made no sound apart from the hissing. Pedley estimated the observation lasted only a few seconds.

Approaching the site where the object had been, Pedley found a circular depression about 9 metres in diameter in the lagoon reeds, with reeds flattened in a radial pattern rotating clockwise, forming a structure he called a 'nest'. He reported the incident to the property owner and then to Tully police. In the following weeks, five additional nests were found in the same area, all smaller than the original, some with clockwise rotation, others counter-clockwise, and a couple with signs of central burning.

The Royal Australian Air Force (RAAF) conducted a formal investigation — the first in the country with sample-analysis methodology. Tully police visited the site the next day (January 20) and reported it to the RAAF; reed samples from the main nest were sent to a laboratory. The RAAF's most probable explanation was prosaic: a 'willy willy' or circular wind phenomenon that would have flattened the reeds and sucked up debris to about 9 metres, creating the appearance of a 'flying saucer'; as for the vegetation, it concluded the reeds had died 'from natural submersion'. The University of Queensland analyzed independent samples and stated there was nothing abnormal, suggesting the nests could result from severe turbulence consistent with the storm systems characteristic of North Queensland at that time of year.

Two qualifications push the case toward ambiguity. First, the RAAF itself noted that depressions left by helicopters produce counter-clockwise rotation, while the main Tully nest had clockwise rotation — which ruled out helicopters. Second, Pedley never accepted the whirlwind reading: he stated that he knew the area's wet and dust whirlwinds well and that 'I know what I saw'. Australian ufologist Bill Chalker —a chemist by training and one of the country's most rigorous investigators— investigated the case for decades and maintains a documentary archive with samples and interviews that has been referenced in international UAP literature.

Es el primer caso del corpus con investigación militar oficial sobre evidencia material física (patrón circular en vegetación), anticipando por una década el paradigma posterior de 'crop circles'. Importa por tres razones: primero, la investigación RAAF + University of Queensland es el caso temprano más sólido del corpus en términos de cadena de custodia de muestras y análisis de laboratorio en territorio civil; segundo, el caso enseña una lección metodológica crucial — un patrón geométrico inusual puede tener explicación natural (line squalls, turbulencia) sin que eso invalide el reporte testimonial original; tercero, la rotación horaria del nido principal descarta explícitamente la explicación de helicópteros, dejando dos hipótesis vigentes (fenómeno natural raro y disco no convencional) sin discriminación instrumental. Es el paralelo cronológico de Westall (mismo año, escolares vs trabajador rural, masa vs solo testigo, sin material vs con material). Tier A por la investigación oficial y la evidencia material disputada; no Tier S porque la explicación natural se sostiene plausible.

It is the corpus's first case with official military investigation of physical material evidence (a circular pattern in vegetation), anticipating by a decade the later 'crop circles' paradigm. It matters for three reasons: first, the RAAF + University of Queensland investigation is the corpus's strongest early case in terms of sample chain of custody and laboratory analysis in civilian territory; second, the case teaches a crucial methodological lesson — an unusual geometric pattern may have a natural explanation (line squalls, turbulence) without that invalidating the original testimonial report; third, the main nest's clockwise rotation explicitly rules out the helicopter explanation, leaving two live hypotheses (rare natural phenomenon and non-conventional disc) without instrumental discrimination. It is the chronological parallel of Westall (same year, schoolchildren vs rural worker, mass vs single witness, no material vs with material). Tier A for the official investigation and disputed physical evidence; not Tier S because the natural explanation remains plausible.
