Original Note:
The vapour trails in the video are an example of condensation trails—or contrails— which are formed when water vapour produced at high altitudes by aeroplane engines freezes as it's released into cold air. Depending on humidity, ice crystals can remain visible for hours. https://fullfact.org/online/chemtrails-vs-contrails/ https://keith.seas.harvard.edu/chemtrails-conspiracy-theory
