Chemtrails Are: Persistent lines of chemical-infused aerosol spray dispersals from typically unmarked planes which are now seen in the sky all over the world.

Unlike normal jet contrails formed from water vapor, chemtrails spread to form a thick blanket of cloud cover, held together by polymer fibers until they reach the ground, contaminating crops, water supplies and humans with radioactive soft metals and dessicated red blood cells which contain active human pathogens.

People across the world are noticing planes crossing back and forth in the sky leaving in their wake a trail of vapor that does not evaporate. These are not your normal commercial airlines following a preordained path from city to city. The mysterious unmarked planes leave smoke-like trails behind them that spread until by the afternoon they have blossomed and grown until the skies have become overcast.
Officials from the Air Traffic Control the EPA and the Air Force will not respond to questions regarding this phenomenon.
