After making the discovery, the pilot, Francois Blanchoud, reportedly
asked

his father, Pierre - a specialist in unexplained phenomena - to take a
flight with him to look it over.

And Pierre reportedly said the crop circle is "authentic."

"The work is huge," he told the Web site."It is not humanly possible."
The owner of the field said he will harvest the corn in 10 days, but the
circle will remain because he will not collect the flattened corn.

See....a marking in a corn field, without tramlines.....

When have you ever seen the stomp......skip....yank....plank
yankers perform in a Corn field without tramlines, on the their
stomp skip yank, stop motion, crop clown shows......NEVER!!!

But they'll CLAIM they did, on their website.....after the fact
of them appearing. That's no fucking proof...!

They have too claim it BEFORE the fact of it being hoaxed
by showing the diagram of it, the one they're going to take
into the field, and put a copy of it, on their Web site. Is that
asking too much.....?

Reason, logic, rationality, and common sense....SORRY....
