@ufoofinterest pointed out this particular "UFO" resembled the water-drop-on-lens caustics seen here:
But those looked bigger and generally more round. I realized that the difference was that the older images were a conventional camera with a 2" wide filter over the lens. Here we just have a phone camera. So it needed a tiny drop of water, and the effect was a bit different:
A shape hovering over the distant light:
Like the "UFO"
Something that occasionally comes up in various conspiracy theories is an attempt to determine temperature from the color something appears in an image or video. This is based on very reasonable science in that the color of light that something like a piece of steel (or really any metal) emits has a very specific correlation to its temperature.
However, as I demonstrate in the above video, this only works well to the naked eye and tends to go wrong in videos or images unless a lot of care is used in the exposure. Since cameras (and cameramen) generally set the exposure for the overall scene then this leads to smaller hot regions of the image being greatly overexposed. Hence they appear a lot hotter than they actually are.
Here's a more focused version of the above video, that contains a direct comparison...
People who think that the World Trade Center was demolished with pre-planted explosives sometimes point to flashes of light that you can see in some videos of the collapses. They say that these flashes are evidence of explosives going off.
This NBC video of the South Tower collapse is maybe the best example of this.
You see one flash near the corner of the building, then another larger flash on the left side here. Both of these flashes exist for only one frame, so they lasted for less than a thirtieth of a second, so we know they are not something like a puff of smoke.
But as we continue though, we see a whole load more of these flashes, including a bunch of them over on the left side that flash in mid-air, so are clearly not attached to the building.
I suppose if you are being imaginative you'd say these...
I had high hopes for "9/11 Unmasked", as it was touted as the "Magnum Opus" of the 9/11 Consensus Panel, and has been highly praised by many in the 9/11 Truth community.
The book is arranged as 51 chapters, which are somewhat difficult to navigate as there's no table of contents (just a list of sections). Each chapter describes a supposed "official story" claim and then proceeds to explain why they think it is incorrect. The chapter claims are often tortuously specific and of dubious relevance, such as: "#29: The Claim That It Was Not Imperative For President Bush to be Hustled Away From the Florida School" or "#16 The Claim That The ForeKnowledge of WTC 7's Fall Was Based on Witness Observations."
The often convoluted nature of these claims might come from the fact that they were written by committee....
This photo from The Unknown Brewing Company made a bit of buzz as it's got a "triangle" UFO, as well as a weird shape made from lights.
But it's just lens reflection, mirrored about the center. You can see this by copying the lights at the top, rotating them 180 degrees, and then overlaying them on the bottom half of the image. I use a "subtract" blend mode, which makes the bright light look dark, and you can see they match exactly with the lights around the building.

It's hard to keep track of the various temperatures involved in discussions around 9/11. So I made the above chart. It's a work in progress, so corrections and suggestions are much appreciated.

One of the great things about "Flat Earth" theory is that it provides some great opportunities for thinking about, investigating, and explaining a variety of basic science concepts.
Now, everybody knows that if you have an alien in your spaceship, the best course of action is to blow a hole in a window, and the alien will get sucked out. Problem solved!
So we all know that if you've got some air under normal pressure, and there's a vacuum next to it, then the air will rush over to fill the vacuum.
But the Earth's atmosphere is under normal pressure, and there's nothing between the atmosphere and the vacuum of space. So why doesn't all the air on Earth get sucking into space.
The answer of course is gravity. Gravity is holding the atmosphere down. But how does that work exactly?...
In something of an experiment, I've made a detailed video focussing on one small claim of evidence. The claim is that the presence of iron microspheres in the World Trade Center dust means that high temperature incendiaries were used to demolish it.
The video explains that you can make iron microsphere by making sparks with steel hitting or abrading things, or by burning some tiny bits of iron in a low temperature flame. I also discuss how some of the spheres found might also have been pre-existing from construction, or might have been created after the collapse during cleanup.
Much of the material in the video comes from the thread: Making Iron Microspheres - Grinding, Impacts, Welding, Burning
In a very positive move, You tube has added a link to the Encyclopedia Britannica article on Contrails to most of the videos that promote the "chemtrails" conspiracy theory.
It's a great article to use as the initial excerpt directly addresses the most common misconceptions about contrails - the idea that they always quickly dissipate.
Iron rich microspheres can be made in various ways. In this thread I investigate some of them, and try to make some microspheres of my own.
