I believe this has merit. Have you ever looked up in the sky and seen the long trail left behind by an airplane? Most folks think it's a condensation trail (con-trail). However a lot of them seems to linger for hours, not only linger but get larger (like spraying great stuff). More and more folks are calling these Chemical trails (chem trails). Ever since, and maybe before WWII, the US govt, and others, have seen the need to control the weather. The conspiracy is that this is the testing or completion of it. It's almost global. Supposedly these planes aren't on that plane tracking website either.
Lets talk about condensation trails. They are made up when warm or hot air is exposed to cooler air. If you watch the skies long enough you'll see that the trail behind a lot of planes will only be so long and disappear as the plane travels. That's what condensation does, if it didn't the air we exhale in the winter would hang around for a lot longer.
Sometimes I listen to a local conspiracy show Saturday nights when I'm out in my shed. The host tells of the chemicals they're using and also how soil tests now compared to years ago shows a significant increase in said chemicals.
He also thinks that the "zero population" crowd may be behind it. What's your take?
