I probably am being dismissive, but I hope I'm not being petty. To explain, I saw a documentary back in the 90s when these crop artworks took off in popularity, and they interviewed the circle makers and believers in paranormal explanations alike. It ended with a self-proclaimed scientist, who had said he thought the circles were the results of a special vortex, being brought to examine a new one that had appeared overnight. He told them that it was a classic case of his theory in action, totally authentic. Then the doc makers brought out the circle makers to explain they had made it and he was talking nonsense. The poor man looked like a complete idiot, there was nothing he could say. It was excruciatingly embarrassing viewing. So that's why I have my doubts.
That sounds like Terence Meaden who was I think a meteorologist, & had some sort of 'vortex theory' around the early 90s. I don't think many people bought it. Of course, some, maybe most, formations are made by stomping, but does that mean they all are?
The more I see & read about this particular incident [it's 2.2 acres, not 22 as I said previously], the more I'm veering towards a non-human cause, or at least, not people with rollers & stomp boards. There seems more to it.
I'd not heard of it before this week, but it seems to have unleashed a shitstorm in the crop circle world at the time, with the 3 participants who supposedly witnessed it being subjected to slander, defamation & abuse on various forums.
These are just some of the later occurrences:
Someone came forward & claimed his team made it but his story doesn't hang together. He's found to have possible links to British military. After the formation appears, the military take a very keen interest with multiple helicopter visits, sometimes coming extremely low & hovering a long time, even when there's people in the field, some start to feel unwell, a radiation detector buzzes a high level warning. There's video of these occurrences. This happened in an area apparently well used by the military & helicopters are not uncommon, but after the formation military activity was extraordinary.
People in hazmat type suits arrive & take samples from the field, an investigator is warned off going to look at it by a non uniformed man due to an unspecified hazard. He tells the investigator there will be a military exercise later in the morning. Sure enough helicopters turn up. He goes into the field anyway, is buzzed by the choppers, feels ill etc.
The formation is in an undulating field & when viewed from above, the circles appear circular, but when measured on the ground many of the circles on sloping ground are in fact elliptical. If the makers were at ground level, they've taken the curvature of the ground into account so that the circles appear circular when viewed from above. Pretty clever.
For anyone interested there's a further video about it
here. It's 77 mins long, goes a bit new agey at the end but gives a good overview of the story & features many of the characters involved.
For anyone REALLY interested, there's a lengthy text interview
here featuring the investigator mentioned above, who also features in the linked video. It's extremely long & the formatting is dodgy but goes into great depth about the incident, people involved, & aftermath. Finishes with his speculations as to what's going on. Likely military testing of directed energy beams, possibly microwave, possibly originating from satellite, is his theory, with the ideal cover story of people stomping, aliens, earth energy etc, take your pick which one you believe.
The above are just a few details, don't want to bore everyone. There's much more should you wish to delve into the rabbit hole.
