Original Note:
The video shows persistent spreading contrails, which form when aircraft fly through air that is ice-supersaturated - that is, the humidity is too high for ice crystals formed from the aircraft exhaust to sublimate. In these conditions, contrails can last for hours. https://scool.larc.nasa.gov/pdf/Contrail_ID_Chart_English_2013_v18_copy.pdf
