The chemtards calls this indisputable proof that chemtrails are real.
The patent (here) is only for a firefighting intervention, not “chemtrails”. That picture is from the inside of a plane for firefighting. That is not close to being proof of chemtrails. Next.
Incidentally, Evergreen Air is NOT part of the CIA. Evergreen Air just purchased a storage facility off the CIA years ago. The chemtards and other conspiracy nutters want to read too much into this purchase. It was a simple commercial transaction and no evidence has ever surfaced that it was anything other than that. Evergreen Air no longer operates and has shut down.
And, WTF would a spy agency (ie CIA) be even involved in something like this for?
