"In late July 2001 circlemakers John Lundberg, Rod Dickinson and Wil Russell created a complex 240ft crop circle formation (pictured right) that was commissioned by broadcaster HTV West for their 30 minute television documentary about the crop circle phenomenon. The formation took approximately 4 hours to construct under cover of darkness and was located in the Beckhampton area, in the shadow of Silbury Hill. The formation consists of eight fold geometry and is certainly amongst the most complex formations to appear in the 2001 season, spanning 240ft and consisting of 178 individual standing and flattened elements. Because of the delicate nature of the design there was very little room for error in the surveying of the formation."
"My own analysis is suggesting that this crop circle, along with two other crop circles of the season, may have been the product of weapons testing. The ground evidence suggests that an energy in the microwave region has been used. Genuine crop circles contain traceable electromagnetic energy (in the mid to high MHz range), which ally with biological and brainwave states (these would be responsible for the changes in chromosomes in crop circles plants, and for the range of physiological affects on visitors); microwave however operates in the GHz range and tends to leave plants and soil sterile (the opposite is true in genuine crop circles). Technology capable of transmiting coded information at such a range was recently switched on in Alaska, under the U.S. military's secret project HAARP. It's just a thought..."
Dunno, but he sounds like a nut to me.
