Contrail - Wikipedia
If water droplets form, they can freeze to form ice particles that compose a contrail. [1] Their formation can also be triggered by changes in air pressure in wingtip vortices, or in the air over the entire wing surface. [2] Contrails, and other clouds caused directly by human activity, are called homogenitus. [3]
