I think some of them are even more mundane than that. There's been a new directive to report UAP. So people have been reporting them, even when they don't think there's anything special. I think Tim Phillips said that some pilots had reported balloons as UAP, even though they thought they were balloons.think we should always keep in the back of our minds, just like the hoax possibility with UFOs, some of these videos were seen and uploaded by UFO enthusiasts within government. Not necessarily those associated with the creation of and knowledge about the video.
And it might not even be the pilots. Perhaps some analyst down the line was looking at this sub and noticed the "UAP" flying around, and remembered the directive, and so they just simply got in the system without any real reason.
Of course, if they are UFO fans (like me) then that might make it even more likely they would report it.
