Harmless or Government Plot - Contrails

Contrails over Westminster

Short for “condensation trails,” contrails are are man-made cirrus clouds that appear when the jet hits a patch of wet air. It’s a similar phenomenon to seeing your own breath during a cold winter day.

Jets emit both solid particles (aerosols) and gas (vapor). The heady mix includes soot, metal particles, carbon dioxide, water vapor, nitrogen oxides, carbon monoxide, hydrocarbons such as methane, and sulfates. Contrails form when vapor freezes around the solid particles from a plane’s exhaust.  ---  Quartz
