Original Note:
Contrails are made up of ice particles and water vapor, not chemicals. “They [contrails] are composed of ice particles that form in the exhaust of an aircraft when flying in a narrow range of altitudes in the upper atmosphere, several miles above the ground” https://www.faa.gov/about/office_org/headquarters_offices/apl/noise_emissions/contrails/
