One of the photos shows what looks to be a blemish in the sky and according to the programme this was confirmed by an Australian photographic lab as being "in the picture" and not dust on the lense or a photographic artifact. It was also sent to the US for research and the blot was confirmed as a solid object that appeared to be enveloped in a cloud of exhaust.
The final piece of this puzzle is the photograph taken by Roy Manifold. He had set up a timelapse camera to capture the sunset off the coast, but found something strange when developed. There appeared to be an unexplained object with an “exhaust cloud” in one of his pictures. According to Roy, these were taken just 20 minutes before Valentich’s last transmission. Experts at an Arizona-based UFO organization analyzed the photos and concluded that the object must be moving at 200 mph, or hovering stationary while the clouds zoomed past at that speed (an equally puzzling feat).
