    1971 Lake Cote / Lago de Cote UFO Aerial Photo

    The full text quoted in #104 says that a 'contact copy' was taken from the original negative in the archive. I take it that a 'contact copy' is the same thing as a 'contact print', as described in this Wikipedia article: https://en.wikipedia.org/wiki/Contact_print The article mentions several...

    1971 Lake Cote / Lago de Cote UFO Aerial Photo

    At the risk of going further down a rabbit hole, I note that the container shown at #142 above, in a Tweet by 'UAP Costa Rica', is actually a drum or cylinder, or more technically a frustum of a cone. This would be suitable for storing a long roll of film, but not for flat printouts, etc. If...

    1971 Lake Cote / Lago de Cote UFO Aerial Photo

    I thought the original negatives were kept in the Costa Rica National Archive? In my experience of archive research it would be unusual for original documents to be allowed out of the premises, let alone to another country. Even eminent academics would usually be expected to visit the archive...

    1971 Lake Cote / Lago de Cote UFO Aerial Photo

    Having seen some of the photographic equipment examples above, I wonder if the 'dark streak' could even be the remains of a filament from a broken bulb. It would be odd to leave this visible in a deliberate fake. Could there be any way in which a piece of disused equipment in the processing...

    Claim: Navy FLIR1 video seems to show Tic Tac antennas

    It could be a white object, as Mick West points out, but equally it could be any other color. There is no reason to think it actually is white, other than the assumption that it is the same object as the 'Tic Tac', which eye-witnesses described as white. The only attribute of the FLIR1 object...

    Bayesian argument to believe in aliens?

    I think you need to explain your thinking on this a bit more. Unless your definition of 'alien visitor' includes 'frequent deliberate or reckless contactor of humans', I don't see how the probability of close encounters, given the occurrence of alien visits, can be high 'by definition'. The...

    Which Gimbal scenario is more likely — 30 NM or 10 NM?

    I think the practical problem with this is that atmospheric refraction is usually very slight, say not more than a few feet per mile. For example, in the Metabunk curve calculator, at a distance of 10 miles the difference between 'drop' with and without standard refraction is less than 10 feet...

    Claim that the Nimitz FLIR1 object could not be a plane because it would have been Identified

    Even a white object will look dark against a background of open sky or light cloud, provided the object itself is not in direct sunlight. Without knowing more about the lighting conditions I don't think we can say that the object in the FLIR1 video is not white. Of course, the video doesn't...

    The Sinking of the Moskva

    The UK tabloid Daily Express has a report on the Moskva sinking which includes the following: I wouldn't describe the Express as a reliable source, even by UK tabloid standards, but I don't think their creativity would stretch to fabricating these details, so I take it that such a statement...

    The Sinking of the Moskva

    For the record, it seems to be a type of 'side cap', which has many names and varieties. Probably the best known to British readers is the Glengarry. https://en.wikipedia.org/wiki/Side_cap According to today's Sunday Times (London), A photograph accompanying the report shows a navy officer...

    The Sinking of the Moskva

    The BBC website has a Russian video showing what it claims to be the crew of the Moskva. The BBC text estimates the number visible at about 100. They are lined up in a row 2-deep. They seem to be arranged in two groups, with taller men at one end and shorter men at the other. The two groups...

    The Sinking of the Moskva

    Thanks. Good point. It still seems a little odd if a Turkish ship was closer to the Moskva than any of the Russian vessels The general 'law of the sea' requires all vessels to give assistance to anyone in danger at sea, unless it would cause serious danger to themselves. I don't know if this...

    The Sinking of the Moskva

    I've seen other reports of a Turkish ship rescuing sailors from the Moskva. This is really very odd. The Moskva was part of a Russian war fleet. If a ship is in trouble one would naturally expect the other ships in the fleet to go to its aid and to rescue its crew where necessary. In WWII...

    The Sinking of the Moskva

    Mendel beat me to it, but usually reliable sources in the UK (BBC, Times, Guardian, Telegraph) are reporting that the Moskva has sunk. The Daily Telegraph states: This must be a huge embarrassment for Moscow, not least because 'Moskva' is the (transliterated) Russian name for Moscow. 'Moscow...

    Kramatorsk Railway Station Attack - Russian Denials of Responsibility

    Dr Mark Felton, a military historian with an excellent YouTube channel, has given examples of Russia using this weapon in recent conflicts. This video mentions usage by Russia in Chechnya, Syria and Yemen, and by both Ukraine and Russia in the present conflict: Source...

    Russia and Ukraine Current Events

    I think that's a very important point to highlight. So often in these situations (like the shooting down of a civilian airliner some years ago) there are claims and counter-claims, and any neutral outsider is likely to think 'six of one and half a dozen of the other', or 'a plague on both their...

    What evidence of aliens would convince skeptics?

    I'm not clear if we are including the case where the ETs actually want us to know they are here. If they do, there are many ways that would satisfy the most diehard skeptic (e.g. me). Classic sci fi movies provide plenty of examples, usually involving giant death rays. A more subtle approach...

    Chernobyl during Russia and Ukraine Conflict

    The word 'trench' tends to conjure up images of the Western Front in WWI, but there are a multitude of reasons for digging trenches. On a basic level, they could be used as latrines or rubbish pits. For defensive purposes, digging a simple slit trench is a relatively quick way of providing...

    Russia and Ukraine Current Events

    Yes, but it's not a war, is it? It's a 'limited action', or some such. How much do the Russian public know about the casualties? It is a cardinal rule that in a totalitarian state, which Russia now is (again), no official statements or statistics can be trusted. We have seen this...

    A Gimbal Glare Explainer

    I noticed a new video by astrophysicist Dr Becky Smethurst, which includes an explanation of diffraction spikes in images from the James Webb Telescope. I don't think she says anything beyond what is discussed above. but her video could be useful as a reference: Source...
