Chilling!
I have watched a lot of alien abduction videos, but this is the one that sticks with me. Partly because it's so simple.
The video shows feeds from four different security cameras in what seems to be some kind of warehouse. At 11:16 P.M., a man is seen approaching a chain link gate. He walks through the gate, then there is a flash of light, and he's gone. All four video cameras show electrical glitches and disturbances during this time.
About two hours later, at 1:06 A.M., the victim reappears in another flash of light (accompanied by electrical disturbances in the other three cameras). He drops to his knees and vomits. Then he gets to his feet, wavers back and forth, then staggers off the way he was originally headed.
It's a perfect miniature three-act play. I'm certain it's fake, but it is so very effective.
The first problem is the tape's provenance. It hails from The Paranormal Borderline, a short-lived television show (it only ran 9 episodes) hosted by William Frakes in the mid-90s. The tape was purportedly sent to the show along with an anonymous note. The man in the tape, and/or the person responsible for mailing the tape, have never come forward.
The Paranormal Borderline had means, motive, and opportunity to create this tape. And that is the most likely explanation for it, frankly. Nevertheless, it remains one of the most effective bits of alien abduction video I've seen so far.
