I'm looking out my office window at an old "contrail" that just won't go away; it just keeps expanding. I'm also seeing other wider cloudlike lines in the sky that look as though they were probably "contrails" from earlier today. Just yesterday I saw another contrail in the same part of the sky which quickly evaporated. Yesterday's weather was very similar to today's so why would some contrails quickly disappear while others persist on similar weather days. My question is this: How do the Normies or "experts" explain persistent contrails? Is there a meteorological explanation they try to put forth? Follow-on question: How do those of us who think this is intentional poisoning of the skies (and thus, of us) explain the process of getting the chemicals into the aircraft in order to create these persistent trails? I am a 30-year plus aviation technician (although not in the airline segment since the 90s) and I don't see how this would get by the people involved in the airline ground support trades. I'm 100% sure there is something seriously nefarious going on here but I can't explain how they get away with it. Another follow-on question: Since bad actors are involved, why wouldn't they just do this crap at night when it's not so obvious? I apologize if I sound like a naïve peasant, but my experience with all the regulations around aircraft certification and operations (including time in the aviation industry as a government employee) makes it difficult for me to explain this to a normie.
