If you want to know what is true about Conspiracy Theories, remember this one: Conspiracy sells.
You people have enough real problems to solve, as I do.
So, please don't worry about the chemtrails hoax.
There are NO chemtrails but Contrails.
Contrails (short for "condensation trails") or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.
The wingtip vortices which trail from the wingtips and wing flaps of aircraft are sometimes partly visible due to condensation in the cores of the vortices. Each vortex is a mass of spinning air and the air pressure at the centre of the vortex is very low. These wingtip vortices are not the same as contrails.
Depending on atmospheric conditions, contrails may be visible for only a few seconds or minutes, or may persist for many hours which may affect climate.
However, IF someone believes that all the governments and the whole scientific world CONSPIRE to destroy life on earth, well, in that case, I'm afraid you need therapy.
You know, some "doctors", "lawyers" "judges" "and "Cosmic Preachers", just love to sell paranoia. It's something like Cosmic McCarthyism.
By the way, DO NOT BUY these people's books, lectures and videos. Remember that most of those are just trying to make $, or just promoting their Egos.
