Original Note:
The formation of contrails require cold temperatures and low humidity, found at the cruising altitude of jets. Turboprop airplanes fly in lower, warmer air where contrails are less likely to form. Jets/planes can appear to be in the same area but only one leaves a contrail. https://airplaneacademy.com/why-do-some-airplanes-leave-contrails-and-others-dont/
