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