Hey, I have been flying as a commercial pilot for a while, the trails are simply a byproduct of the engines, just like the exhaust of your car.

I mean why would they put it in kerosine if they can put it in car fuel. The question is though how do you know they are doing this, is there proof?

Making us more dumb, they would be better off, killing the internet or put something weird in food, oh wait suppose sugar makes more sense 😄

Chemtrails could be true, but so could anything else... so what do we need? Proof... where is it?
