Original Note:
Most commercial jets cruise at 26,000 feet or higher, where temperatures are cold enough that the large volumes of condensed vapor instantly freeze and form visible contrail clouds. Lower altitude aircraft are not going to create them because the temperature is not low enough. https://www.earthdata.nasa.gov/learn/sensing-our-planet/on-the-trail-of-contrails
