The association of "UFOs" and "crop circles" is made elsewhere in this site. The ingredients for such an association are available from the foregoing analysis. For example, if a UFO is employing the Vehicle Masking Device (VMD), it could be both present and unnoticed at the time a "crop circle" is formed. The 60 GHz RF could be up-converted (with a 3X multiplier) to a 180 GHz RF which is exactly centered in an H2O attenuation band. See Figure 1. A controlled antenna (or even an open wave-guide) could heat the water concentrated in the base nodules of stalks causing them to soften and fall in a circular pattern. If simple water absorption of microwave energy is the mechanism involved in these cases, could snow circles be expected next? Humans could make such "crop circles" but they would likely employ the lower attenuation band at 22.2 GHz. Such "crop circles" would appear to contain less fine detail, especially if the human controlled platform is at high altitude to avoid visual detection.

On Tuesday 21st August 2001 two new crop formations were reported near Chilbolton radio telescope in Hampshire, UK. Both were very impressive looking and consisted of a large number of small 'pixels', which when viewed from the air formed a recognizable shape - unlike many other crop formations. One represented a 'human face' and the other resembled a radio transmission that SETI (the Search for Extra-Terrestrial Intelligence) sent from the Arecibo radio telescope in 1974. See Lucy Pringle's Aerial Photograph of the Chilbolton Hampshire Crop Circle.

On July 23-24, 2003, a private scientific research team documented physical evidence that gives us a high indication that Wisconsin Farmer, Art Rantala, actually did eye witness the formation of Wisconsin's first Crop Circle in Mayville, Wisconsin BUT what created them and for what purpose? This is the question that I would like answered

Brad and I both noticed an unusual sound coming from within and around the crop circles. It sounded similar to crackling.
I put together a wav of this sound.
First is the original recording.
Now I slowed the recording down and notice it sounds like the pounding of a heart.
Should we maybe be also then concentrating on recording the noises coming from within the circle for coded messages

Hummm this circle thing has got me completely mesmerized. Look at this!

There were strange goings on at the farm today when a flock of sheep made their own version of a crop circle.
About 100 of the woolly creatures formed an orderly ring - baffling the farmer and passers-by.
Photographer Russell Bird, who captured the amazing scene, said:"I was quite taken aback. I couldn't believe what I was seeing," he said.
"I did see a dog worrying sheep nearby beforehand and the dog ran off round the hedge in a different field, so I don't know if they were discussing that."

He added: "I think there was a chap in Yorkshire who spelled out 'will you marry me' to his girlfriend in sheep by putting feed down."
