Do you know the difference between a chemtrail and a contrail? A contrail is an abbreviation for "condensation trail," which is a visible white vapor trail produced as water vapor condenses from aircraft engine exhaust. Contrails consist of water vapor or tiny ice crystals. The length of time they persist varies from several seconds to a few hours, depending largely on the temperature and humidity.

Chemtrails, on the other hand, are "chemical trails" purportedly resulting from an intentional high-altitude release of chemical or biological agents. While you might think chemtrails would include crop dusting, cloud seeding and chemical drops for firefighting, the term is applied to illicit activities as part of a conspiracy theory. Proponents of the chemtrail theory believe chemtrails may be distinguished from contrails by color, displaying a criss-cross trail pattern and persistent appearance. The purpose of chemtrails might be weather control, solar radiation control, or testing of various agents on people, flora or fauna. Atmospheric experts and government agencies say there is no basis for the chemtrail conspiracy theory.
