There has been a controversy over what has been termed chemtrails from high flying aircraft since the 1990's. The controversy has been over their existence or reality, their content and impact on human and plant health if they are real, their purpose if they are real, and the questions of whom or what group is responsible. Regardless of any conspiratorial controversy and the fact that many are not even aware of chemtrails, the health hazards have been discovered.
Visual Reality Check: Chemtrails vs Contrails
A contrail is a normal occurrence with high altitude aircraft in cold dry air. It is a trail of jet engine exhaust vapors that have become ice particles, forming a very shiny white, narrow trail. This stream dissipates and completely disappears from view shortly. It usually extends no more than 5 to 10 plane lengths behind the aircraft. Contrails' appearance depend on atmospheric conditions, aircraft altitude, and air temperature.
What has been labeled chemtrails are different in appearance and longevity. They may appear from some aircraft while others are not emitting contrails. Although basically white in color, they are not as shiny or brilliant, more of an off white. Sometimes the sunlight passing through them creates different hues. And they appear to be more dense and much longer. They linger long over longer distances, even hours, after the aircraft has passed overhead, usually expanding laterally and becoming much wider than contrails.
So wide in fact that they often merge and become cloud like. If there are enough chemtrails in the sky, the sky becomes hazy. Sometimes these solid chemtrails can be observed slowly falling toward ground level. And this is how air, water, and soil samples for chemical analysis have been collected. Collecting samples at ground levels is impossible with contrails that evaporate at high altitude.
Since the early to mid 1990's in the USA, there have been reports and photographs of unusual chemtrail patterns from various locations throughout the USA and other world wide geographical locations. When official military or government agencies were queried by alert sky watchers, the explanations, if there was even a response, were quite unsatisfactory.
They were usually told that they were seeing contrails and there was no reason for concern. Sometimes they were told they were seeing evidence of Air Force attempts to stem global warming. These unsatisfactory responses led to sincere efforts of individuals to research on their own and network through the Internet.
