I just came across this video that was posted about 5 months ago. It's from Boulder, Australia. I have some reservations about the authenticity of this but wow it's pretty nuts.
When you watch, you'll see the strange blue lights in the sky and then out of nowhere what looks like a portal opens up in the sky and the UFO goes right into the portal. Once the UFO goes through the portal closes and everything is gone.
Now, I'm no UFO expert but this is the first time that I've seen something like this. Video is easily edited these days so again I'll question the authenticity of it BUT if this is real video, this is NUTS!
