Original Note:
The trails left behind by aircraft, often called contrails, are composed primarily of water vapor and tiny ice crystals formed from the exhaust of aircraft engines mixing with the cold air at high altitudes. Contrails do not cause fatigue or health issues. https://www.weather.gov/bgm/WeatherInActionContrails#:~:text=Condensation%20trails%2C%20commonly%20called%20contrails,vapor%20pressure%20at%20low%20temperatures https://www.space.com/what-are-contrails
