Original Note:
Jet engines emit hot and wet air. At altitude it's really cold, below -40. When the hot exhaust meets the cold air, water vapor turns into water droplets which freezes into ice and make the clouds we see trailing behind a plane, called contrails, or condensation trails. https://keith.seas.harvard.edu/chemtrails-conspiracy-theory https://science.howstuffworks.com/transport/flight/modern/what-are-chemtrails.htm
