Chemtrails are trails that come from airplanes. Unlike contrails
they are not condensation but come directly from the aircraft. Chemtrails
have been mistaken for contrails but it has some qualities that are very diffrent.
They spread across the sky, they are wispy not foggy like water vapor, they
make people sick, human white blood cells among other stuff have been found
in them. Their true purpose is still unknown.
