It's really interesting. I've been looking at a lot of archive data of UFO reports from around the world. What I found most interesting that a lot of eye witness accounts (both civilian and military) all have very similar characteristics, such as shape of the craft, speed and in all cases these things are silent. I think the evidence these things are incontrovertible, but what they are is up for debate. The shape in the video you posted matches a lot of shapes of sightings in Scotland and North England.
In terms of the story in your video, that's not something I've looked into. I do have some questions about it you're able to answer?
That supposedly original photo they brought up? Has that photo really been verified as a real, untouched photo? If so I need evidence of that. It looks too good be to be true. That's the holy grail of UFO photos if it's real.
