In this special installment we will talk about the stelae of the planes, which are not chemtrails or chemtrails as some conspiracies indicate.
A lots of Myths and legends have circulated on the Internet for many years about what are those mysterious traces left by many of the aircraft that pass over our heads every day, some leave a white trail and some don't, here we will explain all you need to know about this topic.
Plane trails or misnamed chemtrails
First we must know that what the planes leave and that come out of their engines is a wake, that is not always generated and that is not always the same size or thickness.
This “mysterious” white trail in simple words called contrail, it's nothing but frozen water vapor, It is not fuel or much less chemical trails that "are poisoning us".
These trails are formed when the hot water coming out of the engine exhaust mixes with the cold and humid air of the atmosphere., it condenses and freezes into ice crystals. The contrails are actually a type of cloud of the cirrus type.
During a cold day, expel air through your mouth and you will see steam generated, it's the same basic principle.
In certain situations if the air is humid and cold enough, trails can stay around for a long time and, sometimes due to variations in wind direction, we can see how these get bigger in the air.
Even, this phenomenon could help predict the weather, as a thin, short-lived trail indicates low-humidity air at high altitude, a sign of good weather, while a thick, long-lasting wake reflects moist air at high altitudes and can be an early indicator of a storm.
When are they generated?
Most cases of stelae occur, as we already indicated, when wet and cold conditions meet, but these cases occur on 25 thousand feet altitude or higher.
Some aircraft will leave a trail and others will not, this is generally due to the different altitude they are flying, as well as the different types of engines on the market.
Too, it could be because airplanes, so they fly at the same level of flight, but in different areas, could be in areas of dry or humid air, where only in the second case the stelae will be generated and we could even see stelae generated abruptly, as well as cut and reappear due to changes in temperature and humidity.
The chemtrails conspiracy
While it is true, just like a car or bus, the airplanes pollute the environment with carbon dioxide, sulfur and nitrogen oxides, unburned fuel, soot and metal particles, These are not chemicals meant to poison us., make it stop raining by controlling the weather, generate sterility or give us cancer.

Taking into account the variable and complex atmosphere where winds and turbulence make it unpredictable, for which governments, companies or airlines would like to "fumigate" us, the calculations and possibilities of knowing where and when these supposed chemicals would fall on the population, make this situation unlikely or even impossible, worse at high altitudes.
The reality is that the white trail left by airplanes is nothing more than a reaction that is generated between something cold and hot, as we already saw., so the next you see a stele, rest assured that this plane is passing through a very humid and cold area, while when you see a plane and it does not leave a trail, this one is passing through a not so cold and dry area or this one is not flying at high altitude.
In some more congested airspaces it is common to see many clouds or contrails that even cross each other, and this is due to the different air routes or airways that produces endless streaks in the sky.
