Have you even looked at any of the more serious reports
That don't have any explanation?
The ones science can't even explain?
(I doubt you'd take the time).
Although a large percentage of them ARE man-made; not all of them are (and there-in lies the rub.) Quite a few showed up on royal grounds and British security sites INSIDE the perimeter of their guarded fences and there's no explanantion for that. That's why there's been some interest and a whole lot of covering <up.>
