Just got up. Yeah I will be here off and on for the forseeable future. So here is some more info. As for the tanks, IDK.
I spent some time, and still spend time, in the aircraft industry with a wrench not a stick. My biggest "yeah right fake and gay" issue with Chemtrails is that there would have to be an industry behind it to make it all work. You would need A LOT of infrastructure, equipment, people, etc. Some smart fucker would figure it out and thats that. How to stop that?
Well, when Pizzagate came out all of a sudden it became possible to get thousands upon thousands of people all to know really bad shit and never EVER talk about it. Comped pilots and mechanics and engineers could easily be created to keep it all running.
Alternatively it could potentially be IN THE FUEL. That means that all that you would need is an engine that can handle that fuel additive. This seems very possible knowing what I know about jet engines. The best way would be to make it something that chemically reacts during combustion without causing engine damage. Again, seems possible.
So how do we get to the bottom of this one? Only thing that comes to my mind difinitively would a thing in astronomy/chemestry/physics called Spectral Analysis. I remember it from my college days... back when dinosaurs roamed the earth... Maybe a youngfag would be up to speed more on it.
It is where you can tell the composition of a GAS or fluid with particulates in it by looking at the spectrum of light that comes from it. Its not very advanced science but I don't know how to do it right.
If that were done on many trails and clouds as they pass in front of the sun, using clear skies as a control group then you could measure/identify the various elements in the stuff obscuring the sun relative to eachother and relative to no obsfuscation.
