Original Note:
Contrails typically occur at about the same altitudes as natural cirrus clouds, approximately 25,000 to 35,000 feet. Depending on the temperature and the amount of moisture in the air at this altitude, contrails either evaporate quickly or persist. This plane is at 27,795 feet. https://www.nesdis.noaa.gov/news/do-contrails-affect-conditions-the-surface
