The full NIST report on the fires and collapse of World Trade Center Building 7, NCSTAR 1-9, is nearly 800 pages long. Lots of people in the 9/11 Truth community dismiss it, but very few have even skimmed through it, let alone read the pertinent parts.
Here I do the skimming through part. I do this to give you an idea of just how large and comprehensive it it. Even in this rapid-fire overview you can see the hundred pages they spend on precisely mapping the spread of the fires, and the hundreds more on investigating the possible causes of collapse via simulations. Feel free to pause at any point. All the pages are there.
If you are going to form an intellectually honest opinion on the collapse of World Trade Center Building 7 then by all means read the information provided by Architects and Engineers for 9/11 Truth, and others. But intellectual honesty requires knowledge of other positions before you can reject them. At the very least you should start with the NIST WTC7 FAQ:
https://www.nist.gov/el/faqs-nist-wtc-7-investigation
And then watch the description of how they conducted the investigation
https://www.youtube.com/watch?v=PK_iBYSqEsc
Then you will probably have questions. Be intellectually honest and unafraid. Do your own research. Read the NIST report:

Mylar balloons often look unexpectedly hot or cold on thermal cameras. This is because they are highly reflective of heat. When you look up at them against the sky, they look "hot" because they are reflecting the ground and the sky in the background is very cold. When looking down, like in the "Rubber Duck" UFO video (which may or may not be balloons) then they look very cold because they reflect the very cold sky. In low resolution videos (like Rubber Duck), they look entirely cold.

The white glow that appears around black-hot "UFO" objects in thermal camera footage has puzzled some experts. But it turns out it's not that uncommon. It's just to do with the way the camera boosts the contrast gradients to highlight edges.
So it's not actually evidence of alien warp drive technology.
[CORRECTION] In the video I say the halo effect is a result of applying an optional unsharp mask. In some thermal cameras (particularly older cameras with a BST array), this effect is not optional and is actually a side-effect of the technology used (a rotating "chopper" disk modulates the incoming radiation, and the combined effect is essentially something that incorporates an unsharp mask)
I suspect that the FLIR video, being from 2004, would be more likely to use a BST array. The Gimbal video here is newer. But I'm not sure about the sensors used in either case. Thanks to @MrVipitis for pointing this out.

This is a highly technical explanation of how the Metabunk refraction simulator works. You will need a basic understanding of 2D vector math and code in order to follow it. It is intended for a technical audience.
I'm posting it partly so people, if they wish, can verify the correctness of the simulator, and maybe suggest/implement some improvements.

It's a common thing in 9/11 conspiracies to compare the results of relatively low speed plane crashes with the high speed 9/11 impacts into the Twin Towers, the Pentagon, and the Shanksville field. Why do they look different? they ask. The reason is fairly straightforward, but perhaps it's not really coming across because they are not really thinking about what's going on in the crashes.
So I'm taking a little gamble here, and trying to illustrate some of the concepts using an imperfect scale model (an egg) to hammer home that different circumstances lead to different results.

When you shine a laser beam across the surface of a lake, it is very prone to refraction, but often this is ignored, and the result is declared a victory.
Laser tests are a very poor choice of a test of curvature, when much clearer (and easier) tests are available, such as looking at large objects (like mountains) over water.

While these images might look like a giant streak of light in the sky above some mountains, they actually show something on the ground - the Solana solar power station in Arizona. It's hazy, so you can't see the ground, but the super-bright reflected sunlight shines through.

This is a follow-up to "Some Problems with the UAF/Hulsey/AE911Truth WTC7 Draft Report" published on Sept 7th 2019. https://www.youtube.com/watch?v=7OClixCTdDw
In that video, I noted that Hulsey was using static analysis where he should have been using dynamic analysis and that his dynamic analysis was suspiciously simple.
It has since emerged that he has not actually done ANY real global dynamic analysis, despite several figures in the report being labeled as dynamic analysis - they are actually just simply box physics, set up to look like a particular result based on the static analysis.
The static analysis is also problematic in that it is linear, and the large deformations seen are non-linear.
But perhaps most seriously, there are TWO VERSIONS of the static analysis being presented - one in the report and one in the presentation. These were presented on the same day. The one shown by Hulsey shows a model that will not collapse, and requires the manual removal of columns to force a result. The one in the report is different and has no manual removal. So if they are using two very different models, which one is correct? How do we know EITHER of them is correct? What criteria is used to validate the model? Why is Hulsey using the manually adjusted model in his presentation? Why are there horrific glitches in the geometry in his final result diagram?
Simulating a collapsing building requires a dynamic analysis. NIST did one. It's not perfect, but setting up a dynamic analysis is complex, and runs are computationally expensive. NIST spent months running dynamic simulations.
You can argue their results don't look perfect. But, based on the report and presentation, Hulsey DID NOT EVEN TRY to do a global dynamic analysis. Instead, he used a dubious linear static model, of which there are multiple versions, he (or his students) pushed it way beyond anything that is linear or static, and then they used the "results" of that analysis to manually create some rotating and falling boxes, extrapolating what they thought might happen, which he then labeled "dynamic analysis".

A shaky video, of things that require a lot of magnification. So small or far away. Often out of focus. Low information.
My initial impression is that these look like distant planes, flying directly towards the camera (except that one). They have lights that seem to match. That's my #1 hypothesis. Matches with traffic in the area. But could also be military planes that don't show up on planefinder.net (ADS-B)
#2 is drones, but I hesitate there, as the lights look very plane-like.
