Those retarded fools.
The pilots know nothing about chemtrails. There is no reason for them to know. The chemicals are released automatically when the aircraft is within a pre-programmed "box" of airspace, at or above a given altitude.
I always thought it was the engineers that replenished the chemtrail tanks who were the real culprits in this dastardly scheme. But, apparently, they too are quite ignorant of the whole thing.
Turns out, the chemtrail tanks are replenished by the workers who service the toilets. They, of course, know nothing of chemtrails. The blue toilet juice is actually the chemtrail chemical. Some goes into the toilets, and some is diverted to the chemtrail tanks.
The real question should be: Who is it that decides WHERE the chemtrails are released?
