to the emergence of the commercial jet industry. I know what is a contrail. And these ain’t. An additive has been put into the fuel. My best guess. It’s for the purpose of blocking out sunlight as a means to control the fake global warming scenario. Contrails are short and rapidly disappear. Chemtrails are horizon to horizon and spread out and morph for hours. Years ago, because jet fuel was sooty and visible at takeoff, the fuel was reformulated to clear up the black smoke. So, why has the chemtrail you say is exhaust not ameliorated so our blue skies and our sunshine remain clean and crystal clear? Grunge spewed out into the commons. Maybe you are okay with it.. millions of people are not.’ Link to obvious chemtrail spraying. Please don’t insult my intelligence by stating those are contrails.
