Chemtrails - Chemtrails are a phenomena that happens with jets that are thought to not actually be regular contrails. It has been said that the government is actually dumping chemicals into the sky for a number of reasons, one is in an attempt to control the weather. Normal contrails vaporize and disappear immediatley, but chemtrails actually last in grow. I see them frequently here in VA and I see them pretty much every day where there aren't clouds in the sky, and it seems obvious to me that they are not contrails.
