Original Note:
Contrails are normal and have been a common occurrence since the beginning of jet aviation. Contrails are condensation trails that form when hot, humid exhaust from a jet engine mixes with the cold, dry air at high altitudes. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
