This special program of the show "Best evidence" was broadcasted August 10th, 2007.
It looks at those who claim that jet fuel of commercial and military aircrafts contain secret experimental additives, such as aluminum oxide, for weather modification purposes.
Best evidence - Chemtrails.
The scientific theory behind this claim is that such additives could act like small mirrors to reflect sun rays, thus, slowing down the coming disastrous effects of global warming and climate change.
Discovery Channel's conclusions is that though there is no proven scientific evidence yet that contrails of civilian or military airplanes contain experimental additives and chemicals, they discover that the US military has the technology available to manipulate the weather using these means if they wish to do so through a secret program, as they did in Vietnam during the Vietnam war through a project called "Operation Popeye."
Journalist William Thomas concludes by saying that in the winter of 2005, the United States government established a federal bureau of weather modification in Washington, DC. He says this is a government mandated agency whose stated mission is to modify the weather and climate. Under this rubric, he claims that the government could come out and admit to a chemtrail-type project.
