The pictures depicted are of jet engine contrails. Contrails can dissipate or persist for hours if the air is supersaturated, here is the FAA and EPA fact sheet https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf Here is Ulrich Schumann’s study on contrail formation by high bypass turbofan engines used on airliners https://www.sciencedirect.com/science/article/abs/pii/S1270963800010622?fbclid=IwY2xjawG1gZtleHRuA2FlbQIxMAABHaLfp_10HANwfCtX-3aNZtMgh-g-1fIYbti-djNgw3PD1D4qUtZbggMiWg_aem_683U9KE70SOEFGjQu_1lAw
