This video documentary shows the difference between contrails and chemtrails. Contrails are formed from the condensation of water vapor behind jet aircraft at high altitudes. They can be seen for 15 or 20 seconds before they evaporate and disappear. Chemtrails are formed from the spraying of chemical substances by jet aircraft, also at high altitudes, but these do not evaporate. Instead, they leave billowing clouds from horizon to horizon that gradually spread outward and cover the entire sky with a milky haze, greatly reducing sunlight and visibility. Chemtrails have been a common phenomenon in the NATO countries since the late 1900s, but most people have paid little attention to them, assuming that they were merely contrails. Here is the proof that there is something very unnatural going on in our skies. DVD, 99 minutes.
