Pipe dreams prove nothing. The question is whether anything is actually happening. You guys can't even define how to tell a difference between your imaginary "chemtrail" and an ordinary contrail. You don't know the difference (if any) between "chemtrail" residue and meteoric residue. You are disturbed by ordinary contrails but have absolutely no concern over the definite chemical trails produced by rocket plumes. Presumably, this site is about discovering what is real, not entertaining fantasies. (By no means does everyone here agree with the menace of "chemtrails.")
