This UFO video looked amazing. It was a flying saucer, invisible to the naked eye, hovering by some trees, with bizarre cycling bands of light.
But I quickly recognized it as something I'd only recently discovered - highlights on spider silk that form shapes just like this and are unexpectedly perpendicular to the thread.

In 3 hours on the morning of Jun 17, 2015, between 7AM and 10AM PDT, there were 105 plane flying above 25,000 feet over Yosemite National Park. These are planes passing within 20 miles of 37.81,-119.48 (although it might have missed a few). The video then shows playback with just those plane.
With the traffic for San Francisco and Los Angeles, Yosemite is basically under a giant crossroads in the sky. So it's no wonder it gets a lot of contrails, and sometimes they form grids.
The time bar at the bottom is uin UTC, so it's 7 hours ahead of PDT (Pacific). So 14:00 there is 07:00 in California.
The traffic does not actually stop at 10AM (17:00 UTC) I just stopped tagging planes at that point, but let it run for a while (another 1.5 hours) Based on this, there's probably around 500 planes per day over Yosemite.
The planes that jump around are due to errors in the ADS-B recording - likely when the plane moves from one receiver to another and they are not exactly in sync.
These are almost all regular passenger flights.

New footage of a small jet taken with a FLIR camera appears to show a similar shape to the "Gimbal" UFO video. Combine this with what we know about rotating glares, "aura", and parallax, and it seems like a very good explanation for the Gimbal video is just a distant jet.
The rotation is caused by the gimbal system in the camera needing a de-rotation step to keep the horizon constant. That's probably why the Navy labeled this video "Gimbal" to explain what it showed

The floor trusses of the World Trade Center were heated in the fires and slowly bowed, pulling in the exterior walls as they lost their stiffness. This is a demonstration of how that happens.
A chain is embedded in a cylinder of ice to make it stiff. It's attached to the "columns" with hooks. The ice gradually melts, causing the "floor" to deform, and slowly pull in the columns.

People unfamiliar with car fires are sometimes puzzled by how well they burn. Some resort to wild conspiracy theories about "directed energy weapons" (DEWs). But cars are actually surprisingly flammable — just google "Car Fire" or "Burnt Out Cars"
The wildfire ignites the car, and then the car burns itself. It's as simple as that.

Subsequent analysis during image reprocessing revealed that foreign debris was present in the optical path of the camera system, and can be seen in the photographic exposures. Selected examples of blemish features of this type are shown in Figure 2. A movie showing blemish movement can be seen here. While the image processing steps undertaken as part of this effort may have removed some of these blemish features, users should be aware that blemish features exist in many of the images.

When you view a point light source with a p900 at full zoom it's hard for the camera to focus, so you often get a large out-of-focus "orb" shape. When viewed through atmospheric turbulence, this can ripple. Several videos of Venus (and sometimes stars) show this effect which some people interpret as what Venus actually looks like. Really at full zoom venus still looks pretty much like a small bright light, sometimes crescent shaped.

Dave Falch has a go at debunking the Gimbal "rotating glare" theory in conversation with Chris Lehto. This is my response, explaining that they debunk nothing, because they don't really seem to get it.
