As a boy on the farm in Western Washington back in the late forties and early fifties I used to lie on my back and watch airplanes and jets, for these were still new enough to excite attention, and indeed everything is new to a young boy. I recall often seeing white tails coming out of the jets, and these trails would immediately begin to dissipate, disappearing in just a few minutes: these were called condensation trails, or contrails.

          Nowadays trails behind jets are much more common, and often they do not dissipate for a long time, and when they do, the sky is left a dirty white: hence the name chemical trails, or chemtrails.

          It has been observed that such trails seem to dissipate more rapidly when there are CB ’s about. This is perhaps the major reason that so many people have build or acquired them.
