Original Note:
Persistent contrails form when particulates from jet fuel combustion/exhaust provide ice nuclei for water vapor already present in the atmosphere to freeze to in humid, ice-supersaturated air. Contrails can expand & last for hours by absorbing surrounding water vapor. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf https://www.epa.gov/sites/default/files/2016-10/documents/afd-051013-001.pdf https://keith.seas.harvard.edu/chemtrails-conspiracy-theory https://www.redalyc.org/journal/5117/511766757028/html/
