This volume contains a collection of pictorams, geometric patterns and complex mathematical constructions found in fields in Britain, Siberia, the Argentine and Saskatechwan. The author points to the well-documented accounts of UFOs being observed around the same time and in the same location as crop circle events. He reveals the results of laboratory experiments which have shown the presence of radioactivity in siol samples and definite chemical changes in the stalks of crops taken after the appearance of the strange markings. The book also includes many eye-witness accounts.; This book links together two mysterious phenomena of modern times - UFOs and crop circles - reckons the evidence adds up to the fact that extraterrestrials are involved in crop circles. They are using the extraordinary patterns to send messages of their existence to planet Earth.; No wonder governments have been so keen to support the hoaxers and hush up the reality of the cosmic connection.
