Sometimes you see odd objects flying around the aircraft. During a recent filming, the onboard cameras lens cap escaped from it's storage area. It appeared in 3 frames of the video while Barry rolled the jet. I froze a frame and had some fun with it. Barry grabbed the cap a few frames after this one.
The common structure to all of the California UFO Drone photos is the center circular structure with the "Staves" protruding upward. There are some interesting features protruding from the center of the hub that I will call "Loops". There are seventeen of these "Loops" on this particular "Drone". Earlier photos had sixteen of them, an interesting fact. These "Loops" appear to be directly related to the "Staves" because they are directly in line with and have the same number count.
Caution should be used when analyzing photos like this recent "boomerang" UFO. Note the motion distortions- especially the separate lower ring. Inset photo "A" is a reference showing no distortions due to motion or speed. Inset photo "B" represents extreme distortions due to the shutter speed be lower than "A". Both photos were shot using a fill flash. Inset photo "C" is an enlargement from "B". The front tire and rim in inset "C" illustrates interactions between shutter speed, forward motion, and rotational motion.
