I'll volunteer a few.

Chemtrails? That must be the most stupid thing I have ever heard, because even the apes of the jungle are laughing their ass of because that theory. How about some facts about the matter? Do you imbecile know that there is certain amount of liquid needed to create visible fog? When we add that amount in dimensions of the trails, the amount of liquid needed to make those trails need a tank about five times bigger than the plane itself. Have you seen many planes with chemtanks size of the zeppelin? I know I haven't, so how in the name of god they are able to make those trails? Answer is simple, those trails are made from the humidity of the air, and there isn't any fucking chemicals in them, except those which comes from the exhaust of the motors. Do you even understand that there is laws of physics involved in this matter, and you have to understand it. There have to be at least 0.6 litres of liquid in the cubic meter of the air to make visible fog, no more and no less. Regarding the photos, those trails are at least 6 meters wide, so you can calculate how much liquid is needed. π x rē gives you the area, and (area x length) x 0.6 litres gives you the amount of the liquid/capacity of the tank. If you look google earth you see that there is trails thousands of miles long, so the amount of liquid will be enormous. Where you are planning to keep it? Furthermore, every fucking aeroplane leaves those trails, even rockets like Apollo and space shuttle, and smaller planes. Why and how? Even F1 cars leaves those trails every now and then, so how the hell this is possible? Even that russian meteorite has one, so try to explain that
