Andy Thomas, author of Vital Signs and leading researcher into crop circles, joins the show to explain the phenomenon of crop circles. He gives the history of crop circles and why they appear more in England than anywhere else. These circles may be created by people, but there are many that are far too large are complex to have been manmade. There may be a conscious connection, even psychic projections, from the collective consciousness of mankind that constructs the circles. If it is alien intelligence that is attempting to communicate, he offers an explanation what the crop circles may really be trying to say.
