Conspiracy theorists believe that "chemtrails", the line-shaped clouds emitted from jet aircraft engines, are damaging our health. They think it is a toxic cocktail sprayed from planes in a plot to control the weather, the mind of every citizen, and the food supply.
In fact, the more accurate name for the cloud-like objects is "contrails", as "condensation trails". Aircraft engines emit water vapor, carbon dioxide (CO2), small amounts of nitrogen oxides (NOx), hydrocarbons, carbon monoxide, sulfur gases, and soot. Metal particles were also formed by the high-temperature combustion of jet fuel. When cruising at altitudes in the upper atmosphere, the outside temperature is so low that once the vapor released from the engine, it forms ice particles that are visible from the ground.
In 2016, hundreds of experts in the field of atmospheric sciences were surveyed about contrails: they were provided with the evidence collected on various chemtrail websites and asked to evaluate. 99% of the scientists who took part of the study said they found no evidence of the so-called secret large-scale atmospheric programme (SLAP).
