Bullshit for idiots and incredible stupid people, and it has proven to be that lot better, than you foil hat idiots can prove otherwise. Let me give you some point's to explain:
1. those trails could be seen in all kind of aero planes, military, civilian, air force one etc. in every fucking country from the darkest Africa to the peak of civilizations in Europe, but no one has ever seen even one container of that poison? How this is possible?
2. Those trails could be seen even race cars, like F1 cars, if air humidity is correct for that phenomena. Are they spreading that poison also?
3. To get fog so thick that it could be seen as white clouds, it need to have 0.6 liter liquid per cubic meter. Those trails are at least three times as wide as the engine of the passenger plane, which is 3.5 meters in diameter, so those vapor trails are at least 10 meters in diameter. It makes 78.5 m³ per meter of vapor trail, which means 47 liter per meter, 47 tons per kilometer and so on PER ENGINE. That is a lot of liquid for four engine plane, just for kilometer of trail. Coast to coast flight is something like 3800 - 4000 kilometers, so you need like 178,6 million tons of liquid per engine. Where and how they carry that load?
4. Next thing is to start back pedaling and claim that trails are indeed water from air, but they add poisons with little tiny pipette as they fly. Please study what are half times of those claimed poisons, when you blend them in millions tons of water, and spread them in the air? Or do you mean that this is some kind of homeopathic conspiracy
What you idiots ignore, because you truly are idiots, is laws of physics. Instead of ignoring them, you should study them, because they are number one reason why your conspiracies doesn't work. You try to overrule the laws of physics, and that you simply can't do, because those laws are absolute fact and they rule everything which happens on this universe. It is a fact that there is plenty of chemicals on air, but instead of stupid conspiracies, the reason is the factories, traffic, aerosols and all that crap which gets airborne because of people living, consuming and working in different ways.
What chemicals are in petrol which planes use? You, fucking idiot don't know even that. Aviation fuels consist of blends of over a thousand chemicals, primarily Hydrocarbons (paraffins, olefins, naphthenes, and aromatics) as well as additives such as antioxidants and metal deactivators, and impurities. Principal components include n-octane and isooctane. Over a thousand chemicals, which they don't name because you are too dumb to ask. Now fuck off, you imbecile, go to smell some kerosene..
