Original Note:
These 'Contrails' are formed when water vapour and fine soot particulates from burning jet fuel freeze into ice crystals. In low air humidity, the crystals just dissipate. In higher humidity, they persist, and end up creating visible vapour trails over large areas of sky. https://www.bbc.com/news/blogs-trending-62240071 https://www.aerosociety.com/news/chemtrails-debunked/
