Original Note:
Persistent contrails occur when the humidity of the atmosphere is high, and the contrail ice particles continue to grow by taking up water from the surrounding atmosphere. These can extend for large distances and may last for hours. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf Persistent contrail photos through history: https://contrailscience.com/contrail-photos-through-history/
