Chemtrails Unveiled

Jet fuel contains tiny amounts of substances such as metals, sulfur, and silicon. Although only present in trace quantities, the extreme temperatures inside a jet engine transform them into vast numbers of microscopic particles as the exhaust leaves the engine.

From combustion, the exhaust is primarily composed of larger, irregularly shaped carbonaceous particles. These are relatively inactive compared to the smaller spherical particles. Some of these are tiny metallic species, about 1–5 nm in size. In fact, tens of millions are present in every cubic centimetre of exhaust. Although these small spherical particles are not as numerous as the carbonaceous particles, they dominate the evolution of the trail because they interact so readily with other chemicals produced during the cooling of the plume.

As temperatures drop, the first materials to condense are those least likely to remain in the gas phase, primarily metals. These can be thought of as the first “seeds” of particle formation in the exhaust plume.

As the exhaust cools between about 1,000 and 300 °C, silicon-containing compounds begin to condense onto these tiny particles. This causes them to grow rapidly and develop layered, spherical, onion-like structures. By this stage, silicon can make up a large fraction of the particle mass.

As the exhaust cools further, between 300 and 100 °C, an important chemical step occurs. Sulfur in the exhaust is converted into sulfuric acid in vapour form. This quickly condenses at much higher temperatures than water and coats the tiny spherical particles, making them especially effective at attracting water later on.

As cooling continues between 50 and 0 °C, water vapour in the exhaust begins to condense. The ~20 nm sulfur-coated particles are hygroscopic and highly effective at attracting moisture, rapidly scavenging the water produced by the engine itself to form tiny droplets. At this early stage, the visible trail is formed almost entirely from this engine-produced water, not from the surrounding air.

Further cooling below 0 °C freezes these droplets into ice crystals. As the plume mixes with the surrounding atmosphere, additional water vapour from the air can then condense onto these particles. The hygroscopic particles are extremely efficient at retaining this water, even in air that would normally cause ice to evaporate, allowing the trail to persist and spread into a cloud-like formation more readily.
