People,
On rense.com. at the tippy top, there is a video released by China of some UFOs. About halfway through it, there is a large ufo shooting a very large and rounded radiation above an airport.
What does this mean?
Well, I'll say that radiations spenetrate quite a distance underground, so let's not limite our speculations to the surface.
Those radiations might be harmful to certain biological entities.
Cheers!
