Not to say that Chemtrails don't exist because I actually do believe they do...
BUT... Water vapor does generate on planes flying at high altitudes.
I don't know the technical term but it is actually a major concern for the aviation industry.
What happens is due to friction heat with the plane at high heights, is that mixed with the cold air. Creates condensation, then the cold air freezes
Major issue for planes speedometer and such that require wind flow through the apparatus to function correctly.
Now when this ice meets heat from engines or lower plane friction, it melts.
Now what does small water particles in the air look like?
That's right... Clouds... Vapor trails... Contrails.
.: EDIT :. Wiki for the win! Contrails - Short for Condensation Trail
