Original Note:
This harmless combination of water vapor, in aircraft engine exhaust, and the low ambient temperatures at high altitudes allows the formation of contrails. Contrails are composed primarily 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
