Okay, "no chem-trails from commercial aircraft." In the next sentence you blatantly admit the military has been "spraying people with sh.t for years." Thank you for that. Now it's all so clear to me........
But I can assure you, there is no chem-trails from commercial aircraft.

This is what spraying (military or otherwise) looks like:

The top one is, the bottom one isn't. In fact there are some amazingly beautiful pictures of contrails floating around.
Although the “trade secret” ingredients are well protected by the manufacturer, a recent study contracted by the EPA [10] and other sources strongly imply that these ingredients are salts of barium and/or calcium.

Read em and weep. An additive used in Jet fuel as an anti-static agent can cause extended contrails which could be classified as a chem-trail because of the Barium. chem-trails.... This particular anti-static agent is used in most jet fuel.
Q) How long do contrails last? A) Anywhere from less than a second, up to several hours. If depends on the atmospheric conditions at the altitude the plane is flying. It’s unrelated to the weather on the ground. This is an oft-asked question. The answer is reasonably straightforward, but misunderstanding is common. To understand why a contrail can last as little as a fraction of a second, or as long as several hours, you need to understand what a contrail is, and how it forms. Here’s another question, which has the same answer: Q) How long does a snowflake last? Why is this basically the same question? Because contrails are generally made of ice crystals. Jet exhaust contains a lot of water vapor (the chemical reaction actually produces more water than there was originally jet fuel), and when this gets shot out of the back of the engine at 2000MPH, it hits the frigid air (typically colder than -40 degrees), and the water vapor condenses and freezes, very quickly, into tiny ice crystals, just like snowflakes. So why do these ice crystals sometimes stay around for a long time, and sometimes vanish in seconds? The temperature is well below freezing, so they can’t melt, can they? This is puzzling, because it involves something that most people know nothing about: “sublimation“. Sublimation is when a substance (in this case, water), goes directly from being solid to being vapor (a gas), without actually melting into a liquid. It’s like evaporation, except instead of a liquid evaporating, it’s a solid (ice). If the air is dry (i.e. there is little water vapor in it), then the ice crystals will quickly sublimate into vapor, and the trail will vanish quickly. However, if the air already has a lot of water vapor in it, then the ice will sublimate slower, and the trail will last longer. If the air has so much water vapor in it already that it can’t hold any more (i.e. it’s “supersaturated”), then the ice crystals can’t sublimate, and so the contrail will stay around for a long time. The ice crystals might even attract water from the air, if there is enough, and the contrail will get thicker. Winds might make the contrail spread out to even cover the whole sky. The above is a simplification, as other factors like temperature, pressure, and sunlight have an effect. But it explains the basic reasons why some trails last only a few seconds, and some can last for hours, and spread out to cover the sky. Finally, there is one more way of asking the question: Q) How long do clouds last? This is the same question because contrails are clouds. Contrails are physically very similar to cirrus clouds (except they are long and thin), and so they act almost exactly the same. You see cirrus clouds that last for hours, so why not contrails?
The assertion that the government is spraying noxious chemicals on its own people from high flying military aircraft needs some real substantiation than just reports of seeing contrails in the sky and claiming they are making people sick. While there have been reports of similar activity in the past, merely seeing a jet contrail in the sky does not prove anything. Persistence of contrails is neither an indication that they contain some kind of chemical, nor that it is some kind of spray. As a matter of fact, sailors have known for years to look specifically at the patterns and persistence of jet contrails for weather forecasting. If a jet is flying through air at altitude with a low humidity, the moist air from the jet engine might produce a slight, short-lived contrail. These short-lived contrails are a sign that the weather will be fair. A thick, long-lasting contrail indicates humid air high in the atmosphere, and can be an early sign of a storm
Several scientific studies are also being conducted with respect to contrail formation and their climatic effects. "Cirrus clouds affect Earth’s climate by reflecting incoming sunlight and inhibiting heat loss from the surface. Ordinarily, cirrus clouds are only weakly influenced by most ground-based human activities, because of their high altitude. However, increasing levels of high-altitude jet air traffic may alter the regional climatic effects of cirrus because aircraft condensation trails (contrails) often produce new cirrus, which could differ in their radiative properties."

If one phenomenon gives away the presence of metals in the aerosol, it would be the large number of high altitude rainbows produced by contrail aerosol. Virtually unheard of prior to 1990, bright rainbows, sometimes referred to as “circumhorizon arcs” or more commonly, “chembows,” can be observed regularly wherever jet aircraft fly.
When parts of clouds are thin and have similar size droplets, diffraction can make them shine with colours like a corona. In fact, the colours are essentially corona fragments. The effect is called cloud iridescence or irisation, terms derived from Iris the Greek personification of the rainbow.
Iridescence is seen mostly when part of a cloud is forming because then all the droplets have a similar history and consequently have a similar size. Sometimes iridescence can be seen far from the sun but is most frequent near to it.
