I don't get Stompk. On one hand, he's trying to be a conspiracy theorist, but on the other hand he's doing the complete opposite. Such as stating that contrails forming into clouds is a myth. Try looking up into the sky on a clear day when the jets are out spraying and you'll see for yourself that it ain't a myth that contrails form into clouds. The eye does not deceive.
The eye SEES, then the brain INTERPRETS. Correctly if it is "well-informed" (educated), incorrectly otherwise.
Natural contrails are rare, and never form into clouds. Chemically modified contrails, called Chemtrails, do form gray, disgusting clouds.
