Meaning and Definition
a visible trail of chemical or biological agents left in the sky by aircraft, according to a conspiracy theory.
In conspiracy circles, a chemtrail is purported to be part of a secret large-scale spraying program for purposes like weather modification, population control, or biological warfare, as opposed to a normal condensation trail (contrail).

FAQ
Frequently Asked Questions
The phenomenon labeled as a 'chemtrail' is a normal contrail (condensation trail). The conspiracy theory of a secret large-scale spraying program lacks credible scientific evidence and is rejected by the mainstream scientific community.
A 'contrail' is the scientifically accepted term for the visible line of condensed water vapour from aircraft exhaust. 'Chemtrail' is a term coined by conspiracy theorists who mistakenly believe these trails are composed of chemicals or biological agents sprayed for nefarious purposes.
The persistence and spread of a contrail depend entirely on atmospheric conditions, primarily temperature and humidity (specifically, the ice supersaturation region). Some conditions cause contrails to dissipate quickly, while others allow them to spread and linger for hours.
In formal writing, use it only when directly quoting or discussing the conspiracy theory itself, and always frame it with phrases like 'so-called,' 'alleged,' or 'conspiracy theory about.' The standard term for the phenomenon is 'contrail' or 'persistent contrail.'
