Giant Snake-shape Detected on Radar

Later that day the Australian Bureau of Meteorology’s weather radar picked up a huge serpent-shaped object in the form of a giant ‘S’ about 30 kilometres west of Rottnest Island, which lies offshore Western Australia’s capital, Perth, about 70 kilometres north of Mandurah. Many people watched the strange shape on the Bureau’s live radar feed where it was visible for an extended period as it moved northwest.

The object caused a flurry of speculation and confusion due to its immense size. At somewhere around 80 kilometres long, it dwarfed the 18 kilometre long, 4.5 kilometre wide Rottnest Island it was approaching, and earned itself the nickname “the Rottnest Monster”.

What could this massive oddity have been? Was it just a coincidence that a similarly sinuous UFO was sighted earlier that day?

  1. Raising some very important points. Totally true how sometimes when something like this happens, people get excited… then forget, lose interest etc as we get caught up in the daily grind. made me think and reflect. hadnt seen the light photos (or known about them, just the radar) the plot thickens

  2. Wow they sure did cover this one up!! I live in South Australia and are usually pretty informed in whats going on in this country (especially if its a ufo sighting) and I didn’t even see or hear about this at all. Which tells me that there was a definite cover up going on. There is not that much news going on that’s worth anything in Australia so something like this should have been all over the news but it wasn’t so I smell a rat for sure. Good work Matthew the truth needs to be told.

  3. Thank you for this article. It was a very nice read and I really agree with te points you bring up. Especially the need to question and think about such things on our own. It’s very easy to come up with mundane explanations for all sorts of unknown things, but my feeling is that they just blind us from seeing something new.

    Thanks again for the article and I look forward to read more.

    • Cases like this really do highlight the need to question more. I was amazed at how quickly everyone forgot such a remarkable incident once the government and media swept it under the rug with a very unconvincing explanation. Their ability to do that has ramifications beyond this one incident. It means it is very easy to keep people within their control and steer society away from searching out the bigger mysteries in life and the universe.

      • It is scary how quickly people can forget something so phenomenal and how easily it can be explained away. Thanks for poking holes in the official investigation. It really inspires me to investigate instead of blindly following.

  4. Interesting case, hadn’t heard about it before. The combination of radar images and photos provides very strong evidence.

    If I get it right then what the navy claims is they got this chaff into the air, and not only kept it together like that, but also made it light up and glow, as well as changing its shape while keeping it together. Is that correct? Doesn’t sound likely indeed. And to be honest when looking at the photos that doesn’t seem to be the case.

    You also make a lot of really great points in the last part of the article. Thanks for sharing this case with us in a way these things should be reported.

    • Hi Karim, it sure is an interesting case. Thanks for your comment.

      Actually the Department of Defense just said they “caused” the radar phenomenon with a regular naval training exercise with ships and aircraft. But they made no attempt to explain how they caused it, and the media did not question them or investigate how the could have caused it either. They just accepted their short vague statement as fact and parroted it.

      After the statement was reported, people chimed in to speculate how the military might have done it, and chaff was the usual explanation trotted out. But chaff disperses like a cloud of confetti, and would not move at speed in the wind with a precise shape like this massive object was tracked doing.

      The navy doesn’t have any planes to release chaff with anyway. I don’t doubt that naval warships would have been in the area though, because they have a base nearby and no doubt would have gone to investigate the strange object showing up on radar.

      The military and mainstream media (apart from local community papers) ignored the sightings and pictures of a UFO earlier that morning, despite its obvious similarity and proximity to the radar phenomenon. In fact I don’t think most people familiar with the radar incident would even know there was also photographic evidence of a sighting that day.
