Original Note:
The combination of water vapor in aircraft engine exhaust and the low ambient temperatures that often exists at high altitudes allows the formation of contrails. Contrails are composed primarily of water (in the form of ice crystals) and do not pose health risks to humans. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
