Chemtrails vs Contrails: Poison or Water Vapour?

Share this:

As beautiful summer mornings start bright and clear and the blue skies turn hazy as the morning progresses, the subject of contrails and chemtrails soon manifests in fresh outbursts online. So in this article I’m going to describe the case for both and let you decide which explanation you prefer.

Before I begin, let me be perfectly frank with you. I am profoundly aware that some conspiracy theories do turn out to be true.

I am also aware that the term ‘conspiracy theorist’ was invented as a convenient way to undermine and discredit people who put forward an alternative point of view or who ask awkward questions that put a particular narrative in a bad light, sometimes even exposing it as a lie.

Today’s conspiracy theorist, regarded as an outcast or heretic, can turn out to be tomorrow’s prophet and truth-teller, or simply a scientist who spotted the mistakes in the data.

However, just because one conspiracy theory turns out to be true, it doesn’t follow that all conspiracy theories are therefore true as well. Everything should be questioned, both the conventional narrative and the counter theory that the mainstream media or the government (often both working together) label as disinformation.

With that said, let’s turn our gaze to the skies and look at those contrails, or chemtrails.

Contrails – Condensation Trails

Contrails, short for “condensation trails,” are clouds formed by the exhaust of aircraft engines as they fly through the sky. These trails are mostly made up of water vapour, a natural byproduct of burning fuel in air, much like how a car’s exhaust produces water vapour on a cold day.

To understand why contrails form, it’s important to grasp two key concepts about the atmosphere: temperature and humidity. The atmosphere consists of layers, and commercial aircraft usually fly in the lower stratosphere. In this region, temperatures can be as low as -40 degrees Celsius — an important factor when it comes to contrails appearing.

Chemtrails Vs Contrails

When an aircraft flies, its engines emit exhaust that includes not only carbon dioxide and other gases but also water vapour. In the cold temperatures of the upper atmosphere, this water vapour quickly condenses into tiny water droplets or freezes into ice crystals, depending on the temperature. These droplets or crystals mix with the surrounding air and appear as the visible white streaks in the sky that we call contrails.

But they don’t always appear and when they do, they don’t always appear in the same way.

The reason contrails can look different or be absent on different days is largely due to the atmospheric conditions at the altitude at which the aircraft is flying, particularly the humidity levels.

If the air is very dry, the ice crystals or water droplets quickly evaporate or sublimate back into a gas, and the contrail either doesn’t form at all or is very short-lived. This is why sometimes you’ll see an aeroplane in the sky without a trail behind it.

On days when the air is more humid, especially if it’s saturated, the water vapour from the aircraft’s exhaust can’t evaporate quickly.

Instead, it persists as ice crystals that spread out and form a contrail that can last for hours and even spread out to form a thin type of cloud called cirrus. These cirrus clouds can contribute to changes in the atmosphere, affecting weather patterns and even influencing the Earth’s temperature by trapping heat.

High Clouds

The visibility and duration of contrails can also be influenced by the height of the aircraft. Higher flying aircraft are more likely to form contrails because the temperatures are colder.

The type of aircraft and the efficiency of its engines also play a role. More efficient engines produce less soot and fewer particles, which means there are fewer nuclei for the ice crystals to form around, potentially leading to fewer or shorter-lived contrails.

In summary, contrails are a visible interaction between aircraft engine emissions and the atmospheric conditions of temperature and humidity. They are natural byproducts of the water vapour emitted by aircraft engines at high altitudes, where cold temperatures and varying levels of humidity determine whether a contrail will form and how long it will last.

Chemtrails – Chemical Trails

Now let’s hear the case for chemtrails.

Chemtrails is a theory suggesting that the visible trails left by aircraft in the sky are not merely contrails but are instead deliberate releases of chemical or biological agents.

The theory is that these substances are sprayed for purposes that are often not disclosed to the general public and may include weather modification, population control, or biological or chemical warfare.

The chemtrail theory diverges from the established science of contrails by suggesting that some trails have an appearance or persistence in the sky that cannot be explained by the conditions necessary for contrail formation alone.

It is said that these trails exhibit different colours, last longer than typical contrails, or spread out differently across the sky, which may indicate the presence of additional, undisclosed substances. The theory suggests that changes in weather patterns, unexplained phenomena, and public health concerns correlate with observed spraying activities.

It is argued that certain patterns in the sky, like grids or parallel lines, are evidence of systematic spraying operations. It is also argued that increases in respiratory ailments or other health issues are sometimes connected to heavy days of “spraying,” suggesting a potential link to the chemicals purportedly dispersed.

Those who support this theory often point to the openly documented practice of cloud seeding.

Cloud seeding, a form of weather manipulation, involves dispersing substances like silver iodide, potassium iodide, or salt into clouds to encourage precipitation by facilitating ice nucleation. This practice is often conducted using aircraft, a method that visibly resembles the alleged chemtrail activities.

Supporters of the chemtrail theory also point to previous military and other operations and experiments involving aircraft, particularly during the Cold War.

Operation LAC (Large Area Coverage): This U.S. Army operation conducted in the 1950s involved dispersing microscopic zinc cadmium sulphide particles over a vast area to simulate biological weapon attacks and test dispersion patterns across regions. The public was not made aware of these tests, and the revelation of such activities decades later added to fears of government entities using aircraft to conduct secret experiments on unsuspecting civilian populations.

Project Popeye: This top-secret operation aimed to extend the monsoon season over Laos, Vietnam, and Cambodia during the Vietnam War by cloud seeding. The goal was to increase rainfall to hinder enemy troop movements and logistics. Disclosed in the 1970s, Project Popeye demonstrated that governments were willing to manipulate weather conditions for military purposes, reinforcing concerns about the potential for similar activities in other contexts.

Open-air Testing of Biological and Chemical Agents: Throughout the Cold War, both the U.S. and the Soviet Union conducted open-air testing of chemical and biological agents to study their effects and improve defences against them. These tests, often conducted under high secrecy, sometimes involved aerial dispersal methods, leading to public distrust when they were later uncovered.

Radioactive Tracer Tests: During the 1940s to 1960s, several experiments involved the release of radioactive materials into the atmosphere to track air mass movements and understand the dispersion of radioactive fallout. These tests were initially classified, and their eventual disclosure led to public unease about the health implications and the ethics of such testing.

These operations contributed to a foundation of mistrust in government transparency and ethical standards concerning environmental and public health. The secretive nature of these activities, their potential health risks, and the later admissions by governments that such tests were conducted without informed public consent, has lent credence to theories like chemtrails.


Critics of the chemtrail theory argue that the evidence presented is often circumstantial or based on misunderstandings of atmospheric science. They point out that the supposed anomalies in contrail properties can be explained by the natural variability in atmospheric conditions and that the grid-like patterns are simply the result of standard air traffic routes. Additionally, the large scale of logistics required to secretly load and disperse massive quantities of chemicals globally makes the theory implausible to many.

In response, those who endorse the chemtrail theory call for greater transparency and regulation regarding aerial spraying practices, whether for research, climate control, or other purposes. They urge for independent investigations into the environmental and health impacts of substances potentially being emitted by aircraft.

In the aftermath of Covid-19 pandemic and various attempts by governments in collusion with Big Tech to silence dissenting voices who question the conventional narrative on all kinds of subjects, trust in governments is at an all time low.

However, my personal opinion is that chemtrails do not exist. In time, I may be proved wrong and I’m quite prepared to change my mind if convincing evidence emerges.
