    The Pentyrch UFO Encounter

    The idea that there's a "kernel of truth" behind UFO sightings is the premise of Metabunk: it's how we can debunk sightings with evidence in the first place. When I read an account like Caz Clarke's, I mentally separate observation and interpretation. Thanks for sharing this but I can...

    Debunking Humor...

    The original claim is that it's an IFO, so by identifying the objects, you're not debunking the claim, you're confirming it!

    The Pentyrch UFO Encounter

    From what I can see on the wayback machine, it looks like they changed their comment hosting provider. I also think your expectations of what happens to comments is too high.

    The Pentyrch UFO Encounter

    There's another article in Wales Online by Robert Dalling, Senior Reporter, published 11:51, 22 OCT 2018, UPDATED10:04, 12 MAR 2021. Recalling the events of that day more than two years ago, one witness, Caz Clarke said she could "categorically state it was no exercise". "I will take a lie...

    That blog is a beauty, especially the illustrations. Identified Flying Objects (& Esoteric Truth) In the 1970s, the distinction between fact and fiction completely broke down as a result of years of government fabrications, corporate deceit, media falsehoods and systematic educational...

    Havana Syndrome: "Sonic Attacks" at the US Embassy in Cuba - Mass Hysteria?

    "It is a byproduct, like the sound of a gun, which is not what does the harm." I understand what he's going for, but actually loud noises like gunshots do damage, with symptoms similar to the Havana syndrome, ironically. Obviously unreliable (could all be Russian disinfo agents), but still...

    Gimbal Blender Simulation with Clouds

    I don't think anyone is "afraid". QAnon is a very deep hole that you're not in, and I didn't mean to imply that you were; I'm sorry if I haven't made that sufficiently clear. It's not a character flaw to want UFO sightings to be real.

    Gimbal Blender Simulation with Clouds

    The main point in considering (2) is looking for something normal: away from airports, out on the ocean, a plane going from point A to point B normally flies straight, level, and at constant speed. That's what we are probably going to see. It's also how I would expect flying saucers to move...

    Gimbal Blender Simulation with Clouds

    Yes. Basically, you see this anytime you chase an object that's moving more or less away from you. The thing is, when the UAP is moving sideways, it's no longer technically parallax. Parallax is an apparent movement of an object against its background that is due to the motion of the observer...

    It's also worthy of note that the German re-unification in 1990 came with the promise to not extend NATO eastward.

    Gimbal Blender Simulation with Clouds

    @TheCholla I spent the afternoon setting up a parametrized version of the situation in Geogebra that can calculate the camera slew rate with respect to the clouds. The geogebra file is attached to this post, to download and open in Geogebra/geometry. Most parameters can be modified via the...

    Good discussion about "Disinformation vs Misinformation. Berkeley

    Good discussion about "Disinformation vs Misinformation. Berkeley

    yep, thank you, that confirms what I wrote: Farid never says that '"lies" means disinformation'. Both disinformation and misinformation is spreading of lies, according to that quote. Leifer wrote, "disinformation is nearly always the birthplace of misinformation", and Farid simply doesn't say...

    Gimbal Blender Simulation with Clouds

    F18 at 350 knots at an angle of 4⁰ has a horizontal speed component of 24.4 knots. At 30 nm, the FOV of 0.35⁰ is 0.183 nm wide. 0.183 nm/24.4 knots = 0.0075 h per FOV, that's (×3600) 27s, or about 2 FOV/minute parallax ≈ 0.04 FOV/s. 8⁰ off results in twice the parallax, it's roughly...

    Claim: the greenhouse effect being logarithmic means global warming ain't a problem

    If I want to assess the quality of models that were used in 2000 to predict the next 15 years, I would choose those model runs where the input parameters matched what actually happened in 2000-2015.

    Canary Islands 1976

    Ah, right. I got confused because I didn't see any dates in typewritten text, and one of the stamps is for 22 JUL 1994, which is the expected date but the wrong year. Thank you!
