The Tully "daylight disc" & "saucer nest" effect
The Tully "daylight disk" and what it did: I constructed this montage to show what farmer George Pedley saw at 9 a.m. January 19 1966. The UFO drawing is Pedley's original witness sketch. It is superimposed over a photo of the "nest" effect - a clockwise tight spiral of interwoven sword grass approximately about 32 feet by 25 feet . Initially Pedley only saw a darkened swirling lagoon surface. The "nest" surfaced after a short time and had the quality of a floating elliptical bed of reeds. George Pedley saw the UFO initially about 25 feet directly above the lagoon surface. It rose up vertically about another 25 feet then appeared to depart towards a south west direction, initially dipping slightly and taking off at roughly a 45 degree angle.
Many explanations have been put forward - mating birds such as brolgas, mating crocodiles, upside down helicopters, a "willy willy" (Australian term for a mini-tornado wind vortex - the official Royal Australian Air Force (RAAF) explanation) lifting the reeds into a saucer shape, a hoax (with little evidence author John Van Tiggelin tilts at the idea it was a hoax by Pedley that got out of hand - see his book "Mango Country" (2003)) , and a "plasma vortex"(my friend Jenny Randles argued for this - the same model used to "explain" crop circles) . None of these explanations are tenable.
My conclusion: "The 1966 Tully UFO physical trace case still stands as a classic example of the impressive physical dimensions of the UFO phenomenon."
