I am currently reading Freddy Silva's fantastic book "Secrets In The Fields", and I need to make an edit to the post above to say that the 1996 Oliver Castle video is in fact a fake. Silva explains in his book that John Wayleigh (the person who supposedly originally filmed the Oliver Castle video) approached him at the Barge Inn and showed him the video WITHOUT the crop circle being made, it only showed the balls of light. So there are two versions of the video! Silva then goes on to say that he visited the formation that was shown being "made" in the fake video and the construction on the ground was a mess and he thinks it was clearly a hoaxed formation. Silva also says that an investigation into Wayleigh revealed that he worked at a video editing/animation company.
Since I'm just talking to myself in this community anyway, this raises questions for me as to why the "authorities" would first want to discredit and ridicule the phenomenon to make it seems like they're all manmade (like they did with the Operation Blackbird hoax where they left astrology game boards and crosses in the hoaxed formation, and then broadcast it out on TV), and then do an about-face and fake this Oliver Castle video to make it seem like aliens/balls of light are making them? Just trying to muddy the waters from both directions I guess.
