Original Note:
Contrails can last for hours. If a contrail forms in a saturated atmosphere, the ice crystals are unable to sublimate back into a vapour. If the surrounding air is supersaturated, then the ice crystals will accrete further ice from the surrounding air. https://www.metlink.org/fieldwork-resource/contrails/ https://www.mdpi.com/2076-3417/12/9/4450 https://www.sciencedirect.com/topics/earth-and-planetary-sciences/contrail https://www.space.com/what-are-contrails
