According federal government of the United States, chemtrails do not exist. The white lines in the sky stretching from horizon to horizon are normal jet contrails. These contrails can first appear as small white lines high in the sky then, over the course of hours, expand into small clouds and finally a haze. I suggest that you read the following exposé and ask the tough questions about what OUR government says is NOT happening.
Chemtrails Exposed by Peter Kirby
"Chemtrails Exposed is an in depth look at the history of aerosol geoengineering, which has been to this date, ultra secret and highly classified. What made me attracted to this particular work was the emotion and desperation that Peter paints, as the primary force behind his dedication and this book. His opening is a classic example of the feelings and disbelief that most people who awake to this mega-secret, massively scaled program, experience."
