Tully saucer nest

Case dossier

Pedley's earliest surviving account is the police-completed RAAF form, not the richer versions printed decades later. It records clear sky and hot sunshine, a sighting lasting only a few seconds, no optical aid, and no trail, exhaust or light. The object was an estimate made against nearby treetops. The form says it rose vertically to about 60 feet, then followed a straight southwest climbing path at about 45 degrees. Those details preserve what Pedley told police; they are testimony, not independent measurements.

The chronology is unusually well fixed. Pedley reported the incident to Tully police at 7:30 p.m. on 19 January. At 7:00 a.m. on 20 January he took Moylan to the depression. Moylan contacted RAAF Base Townsville; Flight Lieutenant Wallace sent sighting forms and requested a grass sample. Moylan took that sample at 3:30 p.m. on 21 January and returned the completed paperwork on 26 January. A RAAF minute says no service or civil aircraft were operating in the area at the reported time.

The physical trace was documented but its description changed with time. The official form gives a near-circular depression about 32 by 25 feet, with swamp grass flattened to the surface of roughly four feet of water in curved lines. Moylan recorded no combustion smell, visible scorching, broken trees or tracks into or out of the patch. Pedley said the reeds were green when first seen and brown on his afternoon return. Contemporary clippings in the RAAF file describe the plants as smoothly flattened and later browned, while photographs and later investigators sometimes used different dimensions or swirl directions. The corrected official form reads clockwise; that correction explains much later confusion.

Moylan first considered a small helicopter because Pedley described a take-off, but he also noted a safer cleared landing area nearby and later learned of similar swamp marks attributed locally to a whirlwind. Operational Command then wrote that small isolated waterspouts caused the depressions. This was an assessment, not a demonstrated reconstruction: no weather instrument recorded a vortex at Horseshoe Lagoon, and the file does not show a controlled test reproducing the exact mat. The lack of matching aircraft weakens the helicopter idea without proving a waterspout.

Plant testing answered narrower questions. A University of Queensland botanist reported that the reeds appeared to have died from submersion in a low area flooded by recent rains, with no evidence of parasitic infestation or burning; he explicitly said more wind, current and site information was needed for a complete answer. Separate radioactivity tests publicized through the civilian bureau were negative. These findings make radiation and scorching poor descriptions of the sample. They do not determine what flattened the reeds or whether Pedley's visual report and the plant mat had one cause.

Deliberate manufacture must be kept as a possibility rather than a verdict. People can flatten or weave reeds, and the site quickly attracted crowds, so later marks had poor custody. Yet the police visit came the next morning and Moylan recorded no entry tracks, animal marks or obvious scorching at the main patch. The public file contains no confession, tool evidence or identified maker for the 19 January formation. Human action is therefore mechanically possible but positively evidenced less well than in later British crop-circle hoaxes.

Tully later became entangled with crop-circle culture, but the categories are not identical. The 1966 trace was a floating mat in lagoon reeds tied to one brief aerial claim; the elaborate field patterns popularized in Britain in the 1980s used standing crops and acquired their own hoax, meteorological and cultural history. ABC's 2024 retrospective reports that Doug Bower and Dave Chorley cited Tully when describing their British circle-making. That later influence is reception history, not evidence that their methods were used at Horseshoe Lagoon—or that a saucer was.
