Original Note:
Contrail formation is most likely at altitudes at or above 35,000 feet and at temperatures below -58°F (-50°C), therefore contrails are mostly formed by jets. Turboprop and piston engine airplanes generally fly in lower, warmer air where contrails are less likely to form. https://airplaneacademy.com/why-do-some-airplanes-leave-contrails-and-others-dont/ https://www.gov.uk/government/publications/contrails-and-chemtrails-frequently-asked-questions/contrails
