"The physical characteristics of chemtrails have a different composition than the usual condensation of contrails," said William Thomas (website(1)) a Canadian journalist who appeared on Wednesday's show. An expert and author on the phenomenon, Thomas defined chemtrails as "persistent trails that last for many hours (and are) formed by aircraft flying in close proximities." Chemtrails have been observed for the last four years in North America and now in 12 other allied countries Thomas said.

Besides the countless testimony of witnesses to the unusual trails in the sky, Thomas has spoken with air traffic controllers who told him they ID-ed planes on their radar and had been given instructions by the US military to shift commercial air traffic underneath the haze created by the spraying. Further they were told that these planes were involved in a "climate modification experiment."

Thomas believes an "aluminum oxide" spray may be the cause of the haze. Water and soil samples in affected areas have revealed unusually high levels of aluminum and barium, as well as microscopic particles which Thomas connected with reports of upper respiratory problems. These metals may be being used "to spread sunlight reflected material into the atmosphere," or to "conduct radio waves over the horizon to achieve a high-tech three dimensional radar imaging capability," Thomas speculated. The purpose may be to protect the atmosphere from global warming, he added. That the government cloaks their operation in secrecy is problematical for Thomas because they can't be held accountable for the actions or the possibly related illnesses brought on by the spraying.
