Original Note:
This contrail is normal and has 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, and do not pose a health risk to humans. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
