When looking up Chemtrails I found another one of their Wikilies in Wikipedia; they say "The United States Air Force maintains that the Chemtrail theory is a hoax which has been investigated and refuted by many established and accredited universities, scientific organizations, and major media publications", quoting the 'Contrail Facts' publication by the military which clearly defines contrails as chemtrails.
