It is being featured purely for educational purposes. This video featured on the TV program 'Paranormal Borderline' hosted by Johnathan Frakes and appears to show what some people are claiming to be 'proof of alien abduction'. It is a security video from what appears to be a store. The time is 11.16pm and a worker is seemingly closing up the place for the night. However, when he opens the back gate and walks outside there is an instant, blinding flash right where he is standing and then all of the security cameras are temporarily knocked out, soon resuming their function. They then run for another 1 hour 50 minutes until 1.06am when there is another blinding white flash and all the cameras again get knocked out. When they resume function the aforementioned worker can be seen lying in a foetal position nearby to where he disappeared. He then leans up, vomits, then staggers off disorientated. There is no way of knowing for sure what is happening in this video, however, the possibility that it could be an abduction cannot be ruled out. There is a possibility that the man may have accidentally wandered into a downed powerline and knocked himself unconscious. Maybe it could be an elaborate hoax? What is your opinion?
