I said:"..... it co-incides with the opening of the movie "Signs" ....this would be impossible to hoax".
My word should have been "difficult", instead if "impossible".
Me bad.
Still, I'd like to know how it was done, as I believe it is a well-constructed hoax.
Major researchers have this to offer:
"A Helicopter was hovering over the field at around 3 am
that night. Nobody but military flies at that time of
night in that area.
A 'device' was found in the formation and thought to be
a tracking device (now being checked out).
I have a feeling that the military are behind this one
but lots more data needed first. Apparently its VERY
messy and soil heavily disturbed within the pattern but
clever, very clever."
