From WorldTruth.tv (source): Those long, white streams of persistent, cloudy haze commonly blasted into blue skies by unmarked airplanes are not your typical contrails, says Swedish Green Party leader Pernilla Hagberg. As reported by the Swedish paper Katrineholms Kuriren, Hagberg, the first major political leader to come forward on the issue, has openly admitted that these unusual cloud trails, which fail to dissipate like normal contrails do, are actually a toxic mix of chemicals, viruses, and metals that she has collectively referred to as “Chemtrails.”
According to Hagberg, the sprayings are a joint endeavor by the U.S. Central Intelligence Agency (CIA) and the U.S. National Security Agency (NSA), as well as the Swedish government in her own country, to modify atmospheric conditions via deliberate aerosol spraying efforts. And included in this “dangerous” mix of aerosols are various chemical components, viruses and viral fragments, and metals such as aluminum and barium, which have already been shown to be accumulating in water supplies and soils around the world.

Normal contrails, which are composed of mere water vapor that quickly dissipates after emission from jet engines, are far different from chemtrails, which gradually blanket the entire sky in a sea of white. The following video, put together by the FreeTruth Show, a YouTube-based radio broadcast, contains some imagery of what these chemtrails typically look like in the sky:
