The crop circle phenomenon was first reported during modern times in 1972 when two witnesses, Arthur Shuttlewood and Bryce Bond, sat on the slope of Star Hill near Warminster, England, hoping to catch a glimpse of the strange unidentifyed flying craft that had made this part of England a UFO Mecca for almost a decade. But what they witnessed on that moonlit night was something more extraordinary: a hundred feet away they saw an imprint take shape, a large circular area of plants that collapsed like a lady opening a fan.
Since then some eighty eyewitnesses from as far away as British Columbia have reported the formation of a crop circle, which takes less than twenty seconds to materialize, often accompanied by sightings of unusual lights and structured craft beaming shafts of light onto the field the night before.
Crop circles are sometimes accompanied by a rhythmical trilling sound since captured on tape and analysed by NASA as artificiall in origin. But it was not until a decade later that the phenomenon began to really manifest itself in a quantitative manner. To date there have been over 9000 reported and documented crop circles throughout the world, with some 90% of them coming from England. It is also fair to say that many more may go unreported each year. To date there have been some 9000 crop circles worldwide.
