It is important to distinguish between contrails and chem-trails. Contrails are streaks of condensed water vapor created in the air by jet airplanes at high altitudes. Contrails can exist in two forms: water droplet and ice crystal. Contrails typically become visible about a wingspans distance behind an aircraft flying at high altitude. The trail dissipates quite quickly, usually within a minute or so. Chem-trails, on the other hand, are visible directly behind an aircraft, with little or no gap between the aircraft and the start of the trail. Chem-trails are said to vary from contrails in their length of persistence. Chem-trails do not dissipate quickly; they tend to form into mushy clouds which can block sunlight. Some people are reporting what they describe to be unusual activity in the sky, including jets leaving trails at low altitudes, spray lines creating X's, S's and parallel lines, lines that slowly spread to create a canopy of haze, and reports of unusual smells, tastes, and even illness related to the trails. Also, a reddish-brown gel, dropped from low-flying aircraft, has been observed by people in the past and was even documented on Unsolved Mysteries. Samples of this substance have been allegedly analyzed by Margareta-Erminia Cassani and found to be teaming with biological organisms. Other tests have shown that chem-trails contain more than 3 times the legal level of the toxic substance, barium. Chem-trails may also be one of the primary contributory factors in the collapse of honey bee colonies worldwide. Albert Einstein clearly knew the importance of the honey bee when he said: "If the bee disappears from the surface of the earth, man would have no more than four years to live."
There are currently three main hypothesis for the purpose of chemical spraying in the skies: weather modification, population control, and testing of biological agents on the general pop-lace.
Even if we assume that these trails have nothing to do with eugenics or weather modification, we cannot ignore the fact that our skies are being heavily polluted with aviation fuel emissions that contribute towards a host of different health problems. As far as I'm aware, jet engines run on kerosene (paraffin). The tetra-ethyl (lead) found in aviation fuel and its combustion products are potent neurotoxins that have been shown in scientific research to interfere with brain development in children.
