It's so sad that even after presenting so many evidences and even the patent describing how it all works, you are still saying that it doesn't prove Chemtrail theory? Perhaps that "biegart aviation" seemed you not taking any part in real Chemtrailing agenda?
Note: There are so many disinformation agenda going on and private company like "biegart aviation" would never want its dirty secrets get revealed. So they always put forth deception around it. A private company that modified military aircraft for crop dusting, aerial firefighting, also being used for modifing planes for real chemtrail work.
Well, we are not here to prove anything. We have put everything up^ there for people to see and decide using their critical thinking, outside of the box.
It's upto you to believe it or not. Just take what resonates and leave the rest until you get the whole picture in last.
