Original Note:
Missing context. The length of time that a contrail lasts is directly proportional to the amount of humidity in the air. Dry air, no contrail. In high humidity, the newly formed ice particles will continue to grow in size by taking water from the surrounding atmosphere. https://www.weather.gov/fgz/CloudsContrails# https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
