Crop Circles: The Enigma

Acclaimed writer Steve Mitchell guides us through the very latest thoughts on the phenomenon of crop circles that have been found across the world. We take flight high above the ground at sacred sites such as Silbury Hill and Avebury to get a new and unique angle on this phenomenon. Come and listen to tales of massive circles forming in minutes before eye witnesses and see the evidence for yourself. What causes these enigmatic, often beautiful designs? Are they manmade? Or the work of aliens? Or is the answer to the question even more strange than we have previously imagined?
